I think it's a stupid thing to make those kids breathe it in, no matter how less dangerous it is! It a bad habit, especially to teach it to children. One of the basic rules of lab says: Never inhale directly anything!

John, gravity is nothing but stretch and wraps of space-time fabric! You like it this way?

There is a small of females here, but who can do good science and have a sense of what's going on! Just back'em up man> ! edit: 0.06829% of all members have voted! Sharp!

Well well, increasing number of females! Good to see! What can I say, my dream is coming true isn't it Phi for All?

I'd say in a qualitative way!

Like I said, nerdish sense of judging the reality! Hard to cope! Just forget it, it's not important anyway!

Excuse me for waking up late to reply! Yes, I think computer science is absolutely fascinating and anyone who can get a PhD out of it has a safe and honorable future! I intend to study something related to it, Automatics to be more precise! Good luck and all the bests. Shade!

Yes indeed! And there is a lot more stuff about genetics and genetic engineering that is at the edge of our current ethics! Absolutely! A few days ago I happened to read a book and read some of what you said! But it's always a hard decision to take since after all it is the same as taking out one life, with the difference that it is yet in his/her very beginning. And there are also some diseases which can be identified by DNA testing while still not born, but which diseases might not be lethal till some certain age (50 or some), and some of the worlds greatest figures died before 50, so you could be taking out a genius in there! So there always is a risk and a dangerous probability!

Cl wouldn't work I think but you could find [ce]Cl2O5[/ce] useful. Just to dissolve it in water [ce]Cl2O5 + H2O -> 2HClO3[/ce]

Thanks for uploading this stuff! In a way, everyone is sort of unique and if you try to direct people to choose some stuff which they do by their own free will, then they no longer are unique. Anyway, excuse by nerdish sense of judging things. Cool avatars! Cheers!

I'd go with Sisyphus here! It's not about a literal brain of the cell. It's just a control center where the function of the cell is regulated, and at this point nucleus (genes to be more exact) is the one! Everything is controlled by our genes and as they are located in the nucleus, then there you get the brain of the cell. It truly is a rough analogy but not so hard to be understood!

Yeah, iNow's got a point. After all, this is the ideal place where you can share your ideas!

Well, the nucleus controls everything, so it's kinda main control center. You can think of it as the brain cell too, I see no problem with that!

I got confused at one point! When we were discussing about ozone and it's production our teacher mentioned something that I seem not to understand! He said: "When lightning strikes there is created a voltage of 380V which breaks the molecular oxygen into atomic oxygen and then the atomic oxygen reacts with molecular one and there you got ozone!" I got the second part but not the first! I'm not sure if he's saying that lightning has a voltage of 380V (which is complete madness) or that 380V is enough to break molecular oxygen into atomic ones! What do you guys think?

This shows what it is, or for more complexed informations and discussions you can try: http://ec.europa.eu/food/food/chemicalsafety/contaminants/acryl_guidance.pdf http://en.wikipedia.org/wiki/Acrylamide

I think removing personal interpretation would actually mean the same as removing creative abilities! OK, that is well understood, but I don't think even nowdays we could perform any experiment by which we could say "there you go, this is time!". It's beyond physical and objective features and you have said that too! Well, when science cannot help to determine something in a scientific way, then you're left with only philosophy and personal opinions. Of course this is not the only way of finding out what time is, but yet it's not worthless and it's worth doing as long as there is nothing about it is pure science! That is a typical skepticism! As long as our perceptions for the reality around us are good enough to make us possible understand, explore and live in peace with that reality, I see no reason why such dose of skepticism is necessary! Perhaps our current perception of what time is makes us think of it as an illusion. Some things truly violate common sense, but that does not mean it's not true! If you told ancient men that sun has 1 million times the volume of earth you'd be called a mad man! Same thing applies to time too! Perhaps in the near or far future mankind will had developed a better understanding of what time is and then the word illusion would be absolutely meaningless when referring to time. It's on the human nature always to developed in a better stage and at some point mankind will have completely understood what time actually is. We cannot dismiss possibilities like this! Scientists though that we would never be able to see atom either, but that now has been achieved using "scanning tunneling microscopes". We won't literally see time but we can't simply say we will not understand time since it is an illusion This is a typical example that clearly shows that time is depended form the observer. If event didn't exist neither would time! OK, fair enough! But since in our everyday life seconds, hours, month years refer mean time, then you sentence would better sound "Second, Hours, Minute, Years, Months, and so on are just what is between two events.". You just said that above!

Never ever heard of it:doh:!

It's also interesting to note that beryllium shows slightly different characteristics from the other elements in the group. Example: it does not form strong bases (like all other elements of gr I-II do), it cannot me forged like other elements in his group, it does not have metallic shine like other group elements do. And all that is due to beryllium's small radium which makes him have covalent bond rather than metallic one, changing so his characteristics from the other group members.

There is always a dose of skepticism about everything, and time surely provides such a field that you can describe it in any way you want. But what I'm trying to say with this? Well, first of all, if we don't have a scientific definition of what time is, or that there is nothing that can show how time is like and how it works (since it's subjective), then the concepts of time is still deeply within philosophy. And in philosophy you don't take things for granted! You make thing the way you think it's the most rational! I believe your definition of what time is seems smarter to you then it does to me, and the other way around too. But yet, these are only personal opinions that deal with such a mysterious concept like time. There have been many many views through the history trying to explain what time is, but yet they only explain how the author understood the concept of time. "Time is the number of movements" - Aristotle "Time is a movable figure or eternity" - Plato "Time is a mind dimension" - St. Augustine All of the above try to explain what time really is, but never fully do it! Why! Well, because it's a subjective phenomenon whose existence is directly depended from the observer. There is always something that is not yet clear about time, no matter how deep you try to think of it! Why do we remember the past? Why don't we see the future rather then remembering the past? Why do we use second, and hours, and years to measure the time, when there is nothing absolute which would support our views? After all, why the hell we care about what time is? Or is it on human nature always to seek for more, and try to understand the reality around? I understand what you are trying to say Edtharan, but when dealing with stuff like time, it's better only to express our personal opinions or the views we agree with and try not to give a strict definition to something which itself is a true mystery! I hope you understand! Cheers, Shade

I (and everyone else) would love to be able to get simple definitions so we could define complicated phenomenas, in this case life! It is without any doubt the most complicated entirety of processes possible. I'm saying entirety since life involves a huge variety of processes with by time change due to organism needs and the effect of other circumstances. Every single second something is changing in our organism (as long as we are alive), and the beauty of all is that every process is exactly defined and controlled by genetic factors. Every new protein created, ever new cell created, every cell dying, everything is absolutely controlled. By this harmony in our organism is disturbed by other factors from the outer medium. So where does life come in in what I'm saying? Well, that's life! A complicated entirety of physiological processes. I remember in my first biology class in high school, we talked of three conditions that should me filled in order to make life possible! They are: 1) membrane system ; 2) energy source ; 3) reproductive ability. But it's not as simple as it looks. A lot lot of specifics make these condition not so easy to be fulfilled. The first condition refers, first of all to be able to keep the cellular material inside, a protective shield from outer negative factors that might cause disorders in the well-functioning of the cell, as a gate where organic matter goes in and inorganic goes out etc. The second is quite simple, just the necessary energy able to cause the well-functioning of metabolic processes. And the third condition is need to make life possible to continue. I once have read: "When we fully understand the cell, we will have understood life itself" -D.R. Godard It's an absolutely meaningful phrase since if were able to completely understand how the metabolic processes work on a molecular stage, we would actually have understood how life works at that stage! So what is life? Well, I'd like to know too!

Only after dissolved in water!

Isn't this for HW section?

I just heard this one today! A hot, beautiful chick enters the bar. There's a slow music going and there are only two or three people in the bar. Doll! She goes next to one guy who seems to have drunk a few beers. As he is too drunk, she starts the conversation! Girl:"Hi. What are you doing?". Guy: "Hey! Nuttin' just drinking this magic beer!" Gril: "Really? How so?" Guy: "Don't believe me? Watch!" The guy jumps out of the window and flies three times around one building, then enter again! Guy: "See, not fooling around!" Gril: "WOW! Can I get one?" She has a few beers then tries to fly too! But after jumping from the window she fells and gets cracked! Then the waiter turns to that guy: "Damn Superman! You're a real asshole when you get drunk man"! :D

:D Ruthless! Not after all those child's rights lectures I've followed. So I can fight Lockheed and CrazCo too huh?
