Water Phase Changes

I'm sharing this because it illustrates exactly what happens to water as we vary its temperature by adding or removing heat, including the types of heat necessary to vary the temperature and change its phase:


Just a reminder:

32ºF = 0ºC
212ºF = 100ºC

Attention to the fact that we have two types of heat:

  • Sensible heat: what alters the temperature of the substance
  • Latent heat: what breaks or unites molecules, at constant temperature, allowing gradual phase change till they are all completely separated or united, when the temperature begins to vary again
Summarizing, when the water is getting its phase changed, during all the process, the temperature remains constant, and the energy being added to it or removed from it is responsible for breaking the agglutination of molecules or for agglutinating the molecules, respectively.

Including the 4th state of matter, Plasma, look at the names the phase changes receive:


In Portuguese, they are:

  • Freezing: Solidificação
  • Melting: Fusão
  • Vaporization: Vaporização, Ebulição, Calefação
  • Condensation: Condensação (vapor), Liquefação (gás)
  • Sublimation: Sublimação
  • Deposition: Deposição
  • Ionization: Ionização
  • Deionization: Deonização

O que é Visual Studio?


Não é de estranhar que muitos companheiros de sala de aula que jamais colocaram a mão em ferramentas de desenvolvimento de software saibam o que é Visual Studio, algo que será necessário para a aula de Estrutura de Dados, então deixarei algumas informações de interesse aqui (alguns tiveram algum contato com DevC++ que eu sei).

Muita gente por aí já sabe disso no mercado, mas deixarei o conteúdo em uma linguagem facilitada, para leigo mesmo.

Primeiramente, acho que todos devam saber que das diversas carreiras possíveis na área de Tecnologia da Informação (simplesmente Informática para muitos) é aquela dedicada ao desenvolvimento de software, assim como temos outras dedicadas à infraestrutura (clientes e servidores), banco de dados, etc.

No que confere desenvolvimento, caso ainda não saiba, todo programa que usa em seu computador, assim como tudo que acessa na internet, foi produzido através de linhas de código, similares as que foram vistas no primeiro ano do curso, com as aulas de linguagem C.

Linguagem? 

Pois é, você digita, uma ferramenta chamada compilador ou interpretador transforma o que você digitou em código de máquina, no formato binário, e então o processador é capaz de executar o que lhe foi programado (o código que você digitou em uma linguagem específica).

Há diversas linguagens de programação no mundo, para todo tipo de desenvolvimento, seja para Windows, Macintosh, Linux, Solaris, internet, dispositivos móveis, aparelhos eletrônicos, etc. Alguns exemplos são: C, C++, Java, Pascal, Fortram, Delphi, Visual Basic, C#, JavaScript, PHP, JScript, VBScript, ObjectiveC, Ruby, Matlab, etc.

Algumas delas são utilizadas com tecnologias específicas que facilitam o desenvolvimento de aplicativos. Por exemplo, VBScript e JScript são utilizadas na antiga tecnologia ASP para produzir aplicações para a internet. Seu sucessor, ASP.NET, já trabalha com outras linguagens, sendo as principais, Visual Basic.NET e C#.

Java é uma plataforma de desenvolvimento, que acaba por utilizar uma linguagem de mesmo nome, sendo possível desenvolver aplicativos para praticamente qualquer plataforma (qualquer sistema operacional) ou dispositivo.

.NET é uma tecnologia Microsoft com propósitos similares aos da plataforma Java, embora sua utilização não seja feita em qualquer plataforma com tanta facilidade, pois o foco é a plataforma Windows.

No desenvolvimento de aplicativos para a plataforma Windows dos dias de hoje, seja para seu sistema operacional Windows da sua casa ou de uma empresa, para a internet (com uso de servidor Microsoft), dispositivos móveis (a exemplo dos aplicativos que rodam no Windows Mobile), etc. basicamente, utilizam-se 2 peças que, embora não indispensáveis, são fundamentais para um trabalho facilitado. São elas:

  • .NET Framework
  • Microsoft Visual Studio

O .NET Framework é um aplicativo que hoje em dia já vem instalado no sistema operacional Windows. Ele provê uma espécia de máquina virtual (chamada CLR = Common Language Runtime) onde todo o código por você criado é executado de forma segura e padronizada. É um ambiente de execução de código de forma segura, de forma que códigos maliciosos não tenham plena liberdade de atingir outras áreas do sistema operacional ou outros aplicativos, além de gerenciamento automático de memória e outras facilidades, é um confinamento seguro.

O .NET Framework também provê algo chamado Biblioteca de Classes, que nada mais é do que um conjunto de rotinas pré-prontas, pré-programadas, para você fazer uso quando precisar. Por exemplo, se em um de seus códigos você precisar calcular a função seno da trigonometria, não precisará criar esta função do zero, pois ela já estará disponível pra você, basta pegá-la e fazer uso.

Mas afinal de contas, o que é o Visual Studio? 

Esta ferramenta Microsoft é conhecida como uma IDE (Integrated Development Environment), um software com um editor de texto muito poderoso onde você digita seus códigos em uma dada linguagem de programação, possuidor de diversas ferramentas auxiliares para depuração (detecção de erros de sintaxe de código e de lógica de seus programas), plenamente integrado com o .NET Framework, facilidade na interação com bancos de dados e integrado também com os compiladores das linguagens de programação que trabalham com ele.

Com o Visual Studio, você consegue criar projetos de software completos, sejam eles orientados para a plataforma Windows, internet ou dispositivos móveis.

Uma característica marcante do Visual Studio é a capacidade de criar muitas aplicações com pouca digitação de código. Por exemplo, ao invés de digitar o código para desenhar um componente de tela, você simplesmente "pega" o componente de tela em uma caixa de ferramentas e adiciona ela em sua janela que está sendo criada. Conexões simples com banco de dados podem ser realizadas sem nenhuma linha de código, apenas através dos assistentes do Visual Studio.

As principais linguagens utilizadas com o Visual Studio desde o início do século são Visual Basic.NET, C++ e C#.

C# (leia “C sharp”) é uma das linguagens de programação mais famosas do mundo, e uma das mais amplamente utilizadas no mercado de desenvolvimento de software comercial, disputando diretamente com Java em nosso país, assim como em outros também. C# será a linguagem utilizada no nosso curso de Estrutura de Dados, além da linguagem C como foi também mencionada. É uma linguagem poderosa como o Java, embora esta última seja mais largamente utilizada no contexto multi-plataforma, com o C# sendo utilizado quase que em sua totalidade na plataforma Windows apenas.

Resumindo, nas aulas, utilizaremos a tecnologia Microsoft para o estudo de Estrutura de Dados. Progamaremos em C#, utilizando a ferramenta Visual Studio e as facilidades do .NET Framework.

Onde obter o Visual Studio? 

Vai no Google meu filho... mas pra facilitar, você poderia ir direto no site da Microsoft (www.microsoft.com) e realizar uma busca por Visual Studio, ou mais diretamente na página (www.microsoft.com/downloads).

Vale a pena dizer que o Visual Studio é uma ferramenta profissional, e por isso, é paga, muito bem paga por sinal, pois ela é utilizada por muitas empresas para produzirem seus rios de dinheiro. Contudo, a Microsoft disponibiliza versões simplificadas da ferramenta, para uso doméstico ao invés de comercial, são as chamadas versões Express (www.microsoft.com/express).

As últimas versões do visual Studio são:

  • .NET (2002)
  • 2003
  • 2005
  • 2008
  • 2010

Temos aí 10 anos de Visual Studio integrado com a plataforma .NET, mas é bom saber que o Visual Studio já existia e era largamente utilizado anteriormente, indo das versões 1 até a 6, no final do século passado, foi a ferramenta que popularizou a utilização da linguagem Visual Basic da Microsoft.

Qual versão instalar? 

É bom saber que quanto mais recente, mais "pesada" as ferramentas tendem a ser. Contudo, se você está usando um sistema operacional mais recente, talvez não consiga instalar uma muito antiga (por exemplo, a versão 2005 instala no Windows 7, mas avisa que o faz com problemas de compatibilidade). Se está na dúvida, acredito que a versão 2008 instale no XP, Vista e 7 sem nenhum problema.

Como é dividido o Visual Studio Express, a versão free?

O Visual Studio em sua versão paga é um grande agregado de ferramentas. Na versão free, este agregado não existe, é tudo separado, e você instala apenas o que precisa. As opções disponíveis são, no caso da versão 2010:

  • Visual Studio 2010 Express for Windows Phone
  • Visual Web Developer 2010 Express
  • Visual Basic 2010 Express
  • Visual C# 2010 Express
  • Visual C++ 2010 Express

Acho que fica fácil saber qual utilizaremos, obviamente a versão para C#. Todas elas estão disponíveis aqui: (http://www.microsoft.com/visualstudio/en-us/products/2010-editions/express). A versão 2010 exige registro para poder utilizar depois de 30 dias.

As versões 2008 estão neste link (talvez peça registro também depois de alguns dias): http://www.microsoft.com/visualstudio/en-us/products/2008-editions/express

Tendo o Visual Studio em mãos, provavelmente com o .NET Framework já instalado na máquina (se não tiver instalado, o programa de instalação do Visual Studio irá exigir), bastará apenas conhecer a linguagem de programação que irá utilizar, C# no caso, algo que o professor disse que irá ensinar, então começar a codificar. Sempre tem mais coisas a saber, como Orientação a Objetos, uma estratégia de desenvolvimento que deve ser seguida para programar em C#, mas isso seria conversa longa, e o professor também me disse que irá abordar tal assunto.

Como foi citado, linguagem C será utilizada também, mas isso já não é tanta novidade pois esteve presente nos 2 primeiros semestres do curso.

Fiz o teste por aqui e é possível compilar linguagem C com o Visual C++. Pode ser útil baixá-lo também, caso não tenham outra IDE de programação C.

Caso tenham alguma dúvida, podem perguntar.

Abraços a todos!

Fahrenheit? Aonde é usado?

Eu verifiquei diversos sites para tirar a dúvida se a utilização de tal escala de temperatura era Inglesa ou Americana, e verifiquei que de fato é utilizada nos Estados Unidos e mais 2 países no mundo que utilizam tal escala, a Libéria e Myanmar.

Há várias possíveis explicações para os Estados Unidos não mudarem, não adotarem o padrão mundial que é métrico e com o uso de graus Celsius para medir temperatura. Muito da argumentação existente diz que eles não querem seguir padrão de mais ninguém, os deles serão sempre os mais fortes, ou então, isso faz parte da cultura e a cultura própria não deve ser mudada por causa dos outros. Há muita discussão em torno disso, esta página aqui ilustra bem como os Americanos tratam o caso:

http://www.ask500people.com/questions/why-is-the-us-one-of-only-a-handful-of-countries-to-still-use-fahrenheit-other-countries-are-burma-and-liberia

Este aqui também é interessante:

http://answers.yahoo.com/question/index?qid=20100129221022AA4Kz9u

Medir em Celsius é mais prático, e muitos dizem ser mais preciso também, além de ser um padrão mundialmente aceito, portanto tratando os Estados Unidos como cabeças duras em não querer adotar o sistema mundial por simplesmente ser o que já estão acostumados.

Como mencionado no segundo link, os Americanos querem ter seus padrões, sua própria forma de fazer. Eles podem querer mudar os outros, mas aceitar ser mudado, jamais!

Há quem diga que eles não acabam com o Fahrenheit simplesmente porque não querem ser como os Europeus, o que também seria outra coisa sem nexo, pois esta medida foi criada lá pelo Físico alemão
Gabriel Daniel Fahrenheit (1686–1736), em 1724.

Não vou nem entrar no mérito de outras medidas como libras, pés, polegadas, onças, milhas, etc. pois isso pode ser uma verdadeira bagunça na cabeça de quem só usa o sistema métrico como nós aqui no Brasil e na vasta maioria do planeta. Um dos links que li diz que no Canadá mistura tudo isso.


Dorme com um barulho desses...

De Volta Para a Vida: Frio

Segue aqui um video bem interessante que descreve a morte como um processo que, dependendo das condições, pode ser retardado, desta forma aumentando o tempo que se tem para tentar reanimar as pessoas.

Ele mostra também os relatos de tais pessoas que de fato, morreram, descrevendo 3 casos onde elas revelam o que encontraram do "outro lado da vida".

O foco do video é o frio, e como ele retarda o processo de morte, diminuindo a necessidade de oxigênio do corpo e o ritmo do metabolismo, assim como o ritmo de deterioração das células do corpo, incluindo os neurônios.

The science of love


The science of love

When do you know if you fancy someone? What does love do to your brain chemicals, and is falling in love just nature's way to keep our species alive?

We call it love. It feels like love. But the most exhilarating of all human emotions is probably nature’s beautiful way of keeping the human species alive and reproducing.

With an irresistible cocktail of chemicals, our brain entices us to fall in love. We believe we’re choosing a partner. But we may merely be the happy victims of nature’s lovely plan.

It’s not what you say...
Psychologists have shown it takes between 90 seconds and 4 minutes to decide if you fancy someone.
Research has shown this has little to do with what is said, rather
  • 55% is through body language
  • 38% is the tone and speed of their voice
  • Only 7% is through what they say


The 3 stages of love
Helen Fisher of Rutgers University in the States has proposed 3 stages of love – lust, attraction and attachment. Each stage might be driven by different hormones and chemicals.

Stage 1: Lust
This is the first stage of love and is driven by the sex hormones testosterone and oestrogen – in both men and women.

Stage 2: Attraction
This is the amazing time when you are truly love-struck and can think of little else. Scientists think that three main neurotransmitters are involved in this stage; adrenaline, dopamine and serotonin.

Adrenaline
The initial stages of falling for someone activates your stress response, increasing your blood levels of adrenalin and cortisol. This has the charming effect that when you unexpectedly bump into your new love, you start to sweat, your heart races and your mouth goes dry.

Dopamine
Helen Fisher asked newly ‘love struck’ couples to have their brains examined and discovered they have high levels of the neurotransmitter dopamine. This chemical stimulates ‘desire and reward’ by triggering an intense rush of pleasure. It has the same effect on the brain as taking cocaine!

Fisher suggests “couples often show the signs of surging dopamine: increased energy, less need for sleep or food, focused attention and exquisite delight in smallest details of this novel relationship” .

Serotonin
And finally, serotonin. One of love's most important chemicals that may explain why when you’re falling in love, your new lover keeps popping into your thoughts.

Does love change the way you think?
A landmark experiment in Pisa, Italy showed that early love (the attraction phase) really changes the way you think.

Dr Donatella Marazziti, a psychiatrist at the University of Pisa advertised for twenty couples who'd been madly in love for less than six months. She wanted to see if the brain mechanisms that cause you to constantly think about your lover, were related to the brain mechanisms of Obsessive-Compulsive Disorder.

By analysing blood samples from the lovers, Dr Marazitti discovered that serotonin levels of new lovers were equivalent to the low serotonin levels of Obsessive-Compulsive Disorder patients.

Love needs to be blind
Newly smitten lovers often idealise their partner, magnifying their virtues and explaining away their flaws says Ellen Berscheid, a leading researcher on the psychology of love.

New couples also exalt the relationship itself. “It's very common to think they have a relationship that's closer and more special than anyone else's”. Psychologists think we need this rose-tinted view. It makes us want to stay together to enter the next stage of love – attachment.

Stage 3: Attachment
Attachment is the bond that keeps couples together long enough for them to have and raise children. Scientists think there might be two major hormones involved in this feeling of attachment; oxytocin and vasopressin.

Oxytocin - The cuddle hormone

Oxytocin is a powerful hormone released by men and women during orgasm. 
It probably deepens the feelings of attachment and makes couples feel much closer to one another after they have had sex. The theory goes that the more sex a couple has, the deeper their bond becomes. 
Oxytocin also seems to help cement the strong bond between mum and baby and is released during childbirth. It is also responsible for a mum’s breast automatically releasing milk at the mere sight or sound of her young baby.

Diane Witt, assistant professor of psychology from New York has showed that if you block the natural release of oxytocin in sheep and rats, they reject their own young.

Conversely, injecting oxytocin into female rats who’ve never had sex, caused them to fawn over another female’s young, nuzzling the pups and protecting them as if they were their own.


Vasopressin
Vasopressin is another important hormone in the long-term commitment stage and is released after sex.

Vasopressin (also called anti-diuretic hormone) works with your kidneys to control thirst. Its potential role in long-term relationships was discovered when scientists looked at the prairie vole.

Prairie voles indulge in far more sex than is strictly necessary for the purposes of reproduction. They also – like humans - form fairly stable pair-bonds.

When male prairie voles were given a drug that suppresses the effect of vasopressin, the bond with their partner deteriorated immediately as they lost their devotion and failed to protect their partner from new suitors.

And finally … how to fall in love
  • Find a complete stranger.
  • Reveal to each other intimate details about your lives for half an hour.
  • Then, stare deeply into each other’s eyes without talking for four minutes.

York psychologist, Professor Arthur Arun, has been studying why people fall in love.
He asked his subjects to carry out the above 3 steps and found that many of his couples felt deeply attracted after the 34 minute experiment. Two of his subjects later got married.

My thoughts and comments on this content are in the post immediately before this one, "What is love?"

What is love?


"What is love? Baby don't hurt me, no more" => if you remembered this Haddaway's song from the initial 90s, no, this post has nothing to do with it.

This is a scientific view of what love is, as well as my interpretations obtained by probingly thinking.

Unfortunately, little do we know about ourselves, the nature of the human being. We spend most of our lifetime searching for happiness, ways to achieve it and maintain it, though without ever asking if that is what we are supposed to do or what happiness truly is. Well, we are tempted to do it, after all, it makes us feel good, but without perception, we are directed to do it by religion, society standards and all sorts of influences, a process that first initiates when we are children and begin to perceive the world, learning about it.

I would not talk about this if I did not see any critical problem in it, the lack of knowledge about our human nature, even if that had to be only physically related. Due to that ignorance, human life is commanded by an inexistent world of fantasy, fostered since our childhood. As a result, also, we undergo a lot of emotional suffering which are completely unnecessary.

What do we start learning when we are children and may permeate throughout our existence, till our final days?

  • By direct experience, we learn what happiness and sadness are;
  • We associate happiness with love, and we establish a connection between this feeling and another human, taking it as the source of love;
  • By direct experience, we learn what feelings are, both good and bad ones, and we allow them to command our behavior in daily life;
  • Girls begin to learn that there exists a prince somewhere in the world that is their real match;
  • Boys begin to appreciate girls' bodies, visually, urging for touches, and surrendering to that associated feeling that rises alongside, dreaming too much about it;
  • In lots of societies, also with religious influence, we learn that a couple (a man and a woman) must love each other uniquely, they must swear in church to love each other unconditionally and forever, signing a union contract;
  • As adults, we begin to discover and just wonder what orgasm is, practically everyone searching for it through sexual intercourse practice (you think "how could it be different?");
  • Lots spend a long part of their lives seeking their right match;
  • Some of the youth believe it is impossible to love more than a person in life, till they finally grow up and find out otherwise;
  • When we are committed, we force our partners to be loyal, we oblige that, urge it, through jealousy attacks sometimes;
  • We expect to be loved just as we give love, at the same rate and proportion;
  • When we feel the thrill of observing an attractive woman or man, we tend to surrender to it and forget about its understanding. Some people go beyond, to the bathroom;
  • A highly attractive woman, to men, may be immediately and unconsciously treated as a sexual object, a source of physical satisfaction, but never cogitating anything about the nature of such a natural behavior;
  • We all have dreams and aspirations, all based on feelings. Most things in life depend on how we feel, if an idea makes us feel comfortable, we are able to determine new paths and future goals in our lives, as well as rejecting, refuting anything associated with what makes us feel uncomfortable;
  • Some humans, the majority are women as I see, lead a life that is poorly based on reasoning, their attitudes are illogical, rendering it impossible to comprehend them sometimes. That impossibility is owing to the fact that their day-to-day actions, attitudes, thoughts, speeches, are all based directly on what they feel rather than reasoning or any logical flux. For some of them, it all depends upon how they wake up on a given day; for another given day, their speech and actions may be completely contradictory and opposing to the ones of the other day, everything because they were feeling differently on those given days. Some people do not mind about this, but the more logical ones like me certainly does it and try to understand this inconsistency of personality, everything guided and determined by the feeling of the day. 
  • Some say "Love is something to be felt, not to be understood";
  • Some also say "We do not choose when or whom to fall in love with, it just happens";
  • Etc.

As you can see, all the examples above are feelings related. Feelings are such an important subject since they guide the course of our lives too greatly, what certainly classifies us as humans. Nevertheless, it is worth remembering that most of our pains are related to them as well, not physical, but psychological and emotional suffering, the type of suffering that dominates mankind in all parts of the globe, thanks to the ignorance thereof. 

These two common sayings, "Love is something to be felt, not to be understood" and "We do not choose when or whom to fall in love with, it just happens", at least here where I live in, Sao Paulo, it is frequently heard, it is just a real proof of the ignorance about ourselves, and a sign of the frustrating inability to know and have control over ourselves. Are you happy with that slavery, slave to yourself, your non-sense body signs and circumstances of life? Are you not supposed to comprehend yourself and have the control of it as much as possible? My answer is certainly "no" to the first question, and "yes" to the second, I see it all as feasible, but it is impossible for those ones concerned only about feeling rather than understanding, to those ones who surrender to a feeling just because it pleases and are unable to see through it. What is the implication? Naturally, suffering, sooner or later will manifest, but it will never be understood and avoided, never eradicated easily, and the ignorance will be holding breath with its associated emotional pain. In other words, I see it is possible to lead a more stable life, without the amount of ups and downs we currently observe, guided by uncontrolled feelings and emotions.

Some days ago, I found out that love is nothing else than the action of hormones in our body, our brain chemicals in activity. I do not know about you, but to me, to know that is revolutionary, knowing about this is sufficient to change the course of life of a human being, it is enough to unlearn all the white lies we have been told since our childhood and the false perception of the world as outlined by the examples above. Check this out:

  • Did you know that fidelity may be associated with hormones? 
  • Did you know that the intensity of your love is associated with the level of production of certain hormones you produce?
  • Did you know that the bond between a mother and its child is also strengthened by the presence of certain hormones?
  • Did you know that orgasm is not a magic or an out of the world experience, but rather, the release of certain hormones in the body?
  • Did you know that your daily bliss or sadness is also associated with hormones?
  • Did you think your choice of a lover was based on sanity or you had control over it? You may be mistaken...
  • Etc.

Let us go beyond that:

  • Did you know that your dreams and aspirations may be determined the the chemistry of your body?
  • Did you know that love is not a magic and divine feeling, it is more ordinary than you have ever conceived, also possible to be manipulated by chemistry? 
  • Did you know that orgasm may not be related to a sexual partner, but yes to the amount of certain substances in your body, being possible to be incited by chemistry?
  • Have you ever considered that it is bullshit to swear eternal loyalty to a partner because that may not depend on will only, but most on the chemistry of the body, something that varies from person to person and over the course of time?
  • Did you know that most people call someone Mister/Misses Right because of what is felt at the moment of speech, but that feeling is not everlasting since it depends on chemical composition of the body, something that is naturally undergoing changes?
  • Have you ever asked yourself about the inconsistence of thoughts of some women as being related to a more uncontrolled hormonal activity in comparison with men's? Why do their words have different meanings and importance on different days, with a funny joke seen as unfunny on the next day?
  • Do you appreciate an attractive body? Have you ever wondered the inner thrill you feel is dependent on hormones? How much did you think it was something sane? How sane/stupid are you, man, when you bully someone because you believe he should be as sexually attracted by women’s body as you?
  • Do you not comprehend why the relationship between certain children and their mothers are not as intense as you think it should be?
  • Have you ever considered that evil people, guided by disgust in life, may not be simply motivated by an evil mind or poor education as we naturally think?
  • Why does love fade away along the time? Does that depend solely on your or on your partner’s will?
  • Can you imagine how silly of us being jealous can be?
  • Have you ever thought that many men may pay more attention to the effects of its hormonal activity than to their partners, thus making them truly appreciative of the hormonal thrill instead of the partner, prompting them to be less loyal, ending up being body attracted instead of partner attracted?
  • Have you gotten old and love is gone, only respect remains? Do you wonder why?
  • Do you not think sanity of mind can be related to a more controlled hormonal activity? What to think about people who act on a whim and unreasonably, like following instincts (according to what is felt)?
  • Hey, wait a moment! Love and other feelings have always been treated as something immaterial, but is that really true? Could love be molecules (hormones), as well as other feelings?
  • Etc.

Well, now I think you have notion why I consider that discovery just revolutionary. Indeed, we can go too much beyond if we dedicate some more attention to this matter.

Mankind leads life all immersed in fantasy rather than reality, and the nature of such fantasy always remaining obscure, unfolded, hidden. We are told to love, just because it is good, but what is love? We surrender to what is good experiencing without ever questioning about it. Our ignorance about ourselves brings on inability to comprehend the source of much of our emotional and unnecessary pains.

Regarding what I said above, related to the behavior of a lot of women around,

"Some humans, the majority are women as I see, lead a life that is poorly based on on reasoning, their attitudes are illogical, rendering it impossible to comprehend them sometimes. That impossibility is owing to the fact that their day-to-day actions, attitudes, thoughts, speeches, are all based directly on what they feel rather than reasoning or any logical flux. For some of them, it all depends upon how they wake up on a given day; for another given day, their speech and actions may be completely contradictory and opposing to the ones of the other day, everything because they were feeling differently on those given days. Some people do not mind about this, but the more logical ones like me certainly does it and try to understand this inconsistency of personality, everything guided and determined by the feeling of the day. ",

my interpretation of the situation is explained by the adjective "haphazard" and its synonyms, that describes that scenario properly "random, unplanned, unsystematic, unmethodical, disorderly, irregular, chaotic, arbitrary, aimless, casual, careless, accidental, etc.", an inconsistency of thoughts and respective actions over the course of weeks or maybe days (the consistency does not last as long as the ones of more logical people). Usually, they see/hear/touch, feel, and react, with little reasoning in it; Depending on the hormonal condition of the day, that feel part assumes other states and produce reactions unmatched to the ones of the previous day. Then many men come up and say: "it's impossible to understand women!". Actually, not only lots of women, but sensitive people in general, highly controlled by feelings/hormones (as a matter of fact, uncontrolled).

Have you felt motivated to delve deep into this new world of knowledge? If so true, you had better read what I have read and some similar content, available on the internet today.

First of all, look at this article about the hormone Oxytocin, what was being discovered in 1999:


Look at this envisaged future for mankind too:


Did you know that some people envisage a future wherein mankind will not need to undergo pain, both physically and emotionally? 

Did you know that some folks see as feasible a future where our bodies will be treated as a biological program, programmable, and we would be able to program it so as to control DNA characteristics and all the chemistry that determines our "state of mind and soul"? Nanotechnology, Biotechnology and the like will be far more controlled than it is today, and love, orgasm, happiness will be far more enriched and enhanced than it is possible to conceive today, artificially controlled. Look at this:

3) http://www.paradise-engineering.com/ (click on the numbers and read on)

Did you know that, when it comes to conquering someone's heart, what you say is what matters least? Did you know that there is a recipe to fall in love (oh, how magic and divine this is)? Did you know that?

  • 55% is through body language
  • 38% is the tone and speed of their voice
  • Only 7% is through what they say

Look at this wonderful article, The Science of Love, I do recommend reading this one


Also, the list of hormones involved with feeling in love is described here: 


Yeah man, in the future people will probably buy love in drugstores, will have orgasm without sex since it can be uncorrelated. If you really want an "eternal" partner, maybe that'll be guaranteed.

Despite all that, I think the most important of all in it is the necessity to unmask the illusion, the illogical and unreal love fantasy we learn when we are children and sometimes, we dye with those things still in mind. In the past, I spent many years of my life with a strong idea of what love is, how magical and divine such a sensation was, still believed in the ideal match, divinizing a special girl, always clinging to false conceptions and ignorance, wrong perception of the world as it is. I see that we have 2 choices:

1) To solely be concerned about being happy, to live for that goal. These folks never know a thing about their nature as a human being, it is all based on guessing and the truth varies from person to person, depending on how things are felt and this way assimilated. This should not be reliable parameters for learning, every human being, though similar, has different hormonal activity and that ultimately determines our assimilation, our fondness, liking, aspirations, desires, observations, etc. thus everybody ends up with their unique truths instead of a universal truth valid to everybody independently on one’s mood.

I do not deny how good it is to surrender to the good, but as time goes by, more and more I am inclined not to surrender blindly to anything in life, it is crystal clear that this may lead to stupid states and actions, mistakes, emotional pain, inflicted suffering on you and your partner. These folks suffer, but they are unable to comprehend how certain things are unnecessary, as well as how to avoid or skip them.

2) To seek to comprehend the world just as it is. If you are able to renounce surrendering blindly to the pleasures of life, both the physical sensorial one (through the five senses) and the emotional one, you may be able to see through it, to go one step further and become more knowledgeable about the underpinnings of the human being. If knowledge is a trigger to satisfaction to you, you are eligible to follow this path more easily.

Actually, you can combine both choices, dosing them in right amounts in the course of your learning experience of what life is. 

Summing up, 

Love is not divine, and may be as material and ordinary as the water we drink! We are not half of what we think we are! You feel love as divine, you attempt to make it so, but nothing do you know about the consistency of such a thing. That false assimilation makes you treat someone as a deity, but that one is not more important than any other person in the world. With this in place, all the love fantasy and dreams you develop are rendered nonsense. You love someone because your brain chemistry dictates that, and if you think a little bit deeper about it, you will understand that your “Mr. / Ms. Right” can be anybody in the world, there is no somebody unique to whom you are united by fate and will turn up sooner or later in your life. 

Sometimes, a mere smell is able to awaken fantasy in your mind and trigger circulation of hormones in your body, and you, poor one, fall in love or feel sexually attracted without comprehending what is going on. At times, a mere look at a slim body does the same. Lucky you if that is an appropriate person, otherwise, blindly, you may be insisting on someone unworthy of your attention, and you will carry on with that for long because you deeply believe in your "divine" feelings that reveal to you what to do. Oh, come on, now you know what it is... If a mere smell or look can captivate your attention so as to transform yourself and originate such a surge of uncontrolled feelings, without any command of yours, completely misdirected, you definitely have to learn more about yourself, but you do not learn this at school or at home, especially soap-operas that indirectly dictates human's behavior.

Depending on the concentration of Oxytocin and other chemicals in your body, you are able to love the whole world boundlessly and the only thing that dictates you must “belong” to one person only may be your religion, your selfishness, or an idea assimilated when still a little kid that perpetuates throughout life. Your partner may have lower levels of Oxytocin compared to yours, so is it really fair to demand the same level of loyalty from him/her? When a kid, you learned it must be demanded, but now you know why that may not happen and you can start to wonder if you are doing the right thing. Among the animals, humans are the only ones that set up the virtual contract that reads “you must belong to me only.”

In the future, perhaps we shall be able to love mankind as a whole instead of fostering great feelings exclusively for a partner, what is certainly selfish of us. Maybe, as those web sites aforementioned tell us, mankind will have more control of its emotions, pain, dictate what wants to feel and in what amount, buying happiness in the drugstore once we know what triggers it, after all, it is all chemistry, atoms and molecules that make us feel on cloud nine, exhilarated, as much as illegal drugs can do. 

Do I have anything against love? No, I do not, but I do favor opening up our eyes to the truth of our existence, I am an eternal truth hunter through the light of comprehension. I do not live to be happy and this is it. I see life as something much more meaningful, a real set of opportunities, avenues to go through, a great chance to enrich ourselves with knowledge and mindfulness that ought not to be missed. Sometimes, I also think that we should not waste so much time in the pursuit of happiness, of a partner, especially if we are naturally not unhappy, and there is no realistic law that determines our path to happiness is through the opposite sex. Does it make sense to lead a life with the sole purpose of igniting your hormones for personal satisfaction? Now that I know the key influence of chemistry in the composition of our happiness, much of the illusion developed since I was a child has been pushed aside. I feel more independent and strong inside, and the best, without depending on anyone to make me so. Our time in this world is limited, and it should be better utilized for something more useful such as understanding oneself, the proper existence, having the command of it, and why not, to endeavor to seek the reasons behind our existence in this universe, our destination and best path to follow. Some people prefer just to be happy, to maintain pleasant hormonal activity on and on... I do not!

I just hope to have 100% control over my feelings and how I react to them in the coming years. I have already succeeded in it to a great extent, by opening my eyes to its real nature through the light of Buddhism. Now, with this scientific view of feelings together, I am probably going to be more successful in heading to 100% in the coming years.

Do you think I am crazy with all that above? Haha, I will not believe it unless you convince me with solid argumentation, otherwise, to me, your certainty will remain blind, guided by what you feel, therefore, without sense, mutable and uncontrolled. Some people feel and utter; some people think and talk. When the search for clarity is what matters, the latter is my option. I know certain things are uncovered by reasoning, requiring a different way for learning, but we are definitely not talking about this here.


Ah, time has shown me that there are two types of people with whom my relationship is too hard to maintain, the ones of BIG ego and the highly sensitive ones. Why? I'm usually very logical and I like to get down to the core of everything. 

- The big ego ones usually begin to refute questions earlier and assume I'm challenging them for a battle  when not, and sparks go off; the ignoramus of this category want to emotionally be correct in what they say, sometimes speaking louder than you. I try to be logical, I do not accept that behavior of theirs, and sparks go off again; 

- The highly sensitive ones (a lot of women unfortunately, some men included) time and again lack sense to me. Whereas I search for clarity in everything, they get lost in despair or vanity within their emotional universe, and they come up so fiercely with bullshit, trying to make me comprehend what makes no sense at all. The same holds true for some men of this category. As I see, intelligent and well educated women are usually more logical and have a behavior that I do appreciate, without emotional hysteria, without getting sunk in their own tears. Also, these folks get easily hurt by me, not because I hurt them, but rather, because they are way too much sensitive and assessing their own little reasoning makes them feel down, and they assume I always want to be superior to them, when actually, I just want to get down to the core of what we think and speak.

How to keep the hormones under control? Medicines or self-awareness? I think medicines are for extreme cases, and I do think that mankind terribly knows nothing about itself, what calls for self-awareness. Fortunately, my insatiable search for resolution of my inner problems (lots of them emotionally related), started almost 10 years ago, found its way through the light of Buddhism and Gnosis. Those things direct you to your inner being, makes you survey your inside universe and comprehend yourself better, weaknesses and strengths, and little by little human life is understood, and we learn to identify the nonsense in us, control it, and consciously change it, purging the emotional illusions. This has been working for me. If it does not work for you, there should be another way, but I am pretty sure that any way you choose something is mandatory: willpower (this is not asking God to help you, this is an inner action, self motivation).

I wish enlightenment to all you, may we be rid of suffering and illusions in our lives, it is my wish to all sentient beings!

Regards!

Special thanks to my teacher at the university, Carlos Alberto Bautzer, the one who mentioned in class "Love is chemistry, have you ever heard of Oxytocin?" This revolutionary sentence prompted me to do some research and begin to see the world of feelings with a different and more realistic perspective, eradicating the illusions and fantasy that lead us to unnecessary pain and unrealistic conceptions. Truly, life is not fairy-tale, and though we say we know it, we do not experience that truth, but I shall try to make it differently. 


Thank you man!
