    Medical Question about Nutrition and Brain Development

    First of all, to answer your question, yes certain types of nutrition are beneficial to brain growth (eat your fishies!). Someone else can elaborate on this further, because things like folic acid when you are still in the womb etc also have an effect. Second of all, your prefrontal cortex...

    Multipage Posters on Cellular Respiration, Photosynthesis (Calvin Cycle) etc

    Since I'm such a geeky person (trust me, my computer desktop background are digits of the pi), I'm looking for multipage posters (several A4 sheets of paper) in which I can just print out, tape them, and stick them on my wall. As said in the thread title I am looking for posters for the...

    Can Graph Theory Exist Without Visual Graphs?

    I find it the opposite, I think that modern mathematics is growing more pictorial. Now every single explanation has a graph to go with it, and textbooks usually more graphs than ever, since the theory is more developed, with new aspects on calculus etc.

    Do you remember the formulas for

    Take the IB exam, and you get Information Booklets which include most of the formulae that you need. What I personally do is just work out the bare bones, then derive them if needed during the actual test. Saves lots of time for more practice.

    Cos^2 - Sin^2 = Cos(2a): Shaum's Solution

    If you know complex numbers [including de Moivre's theorem (great chap, wasn't he) and Binomial Theorem], you can find the exact angle of any sin/cos/tan in surd form, and you can prove any double angle/triple angle/quadruple angle etc angles. Back on topic though, yes those identities are...

    Medical Understanding the Unique Functioning of My Mind: A Scientific Exploration

    Well I have a similar thing to you, in such that I can recall every single melody/tune/music heard once, but I suppose photographic memory is better. BUT I can save money on iPods and other mp3 players, because I can go through them in my mind, stereo effect. Guess what too, I'm dyslexic, and...

    Medical Where is Water Stored in the Body & Its Effects on Athletes

    Cells, every single cell contains water. Without water in cells...well, you can guess what happens. Athletes should not drink large volumes of water during intense exercise or right after exercise mainly for one reason: You are sweating profusely and you are losing salts. By having a large...

    A level chemistry - ligands, d-block elements and complexes

    Seems correct from first glance. As far as I can deduce, this should be an octahedral complex, so if you want to work out the structure by drawing a Lewis diagram, you should be able to double check.

    Discover the Science Behind Acidic Water Molecules | Innovations Report"

    What makes things acidic is H+ ions, right? That's only correct to a certain extent. When we refer to H+ ions, we refer to the hydronium ion, H3O+ as some have said. This is what makes acidity. You can't have acidity without water. So you can have the most intense acid in the world, with a pH...

    Medical Neuroplasticity in brain development

    I would say neuroplasticity is indeed something you can bet on. I mean, I have no sufficient hard evidence or any scientific articles to back me up, but: look at chess players, they can be brilliant at chess, they brain has been so reprogrammed into, their brain is highly specialized in playing...

    Two hydroxides doesn't matter in this problem

    First of all, work out the reaction, what is the stoichiometric ratio of this reaction. Secondly, work out the number of moles in both substances then it should be basic plugging and chugging.

    Periodic table of the elements

    One of the unifying themes in chemistry is periodicity. There are patterns EVERYWHERE in the periodic table. You can work out [i]trends[.i] of many things, such as: Atomic radii ionic radii Electronegativity First ionization energy reaction with water reaction with chlorides and much...

    Medical Just a random question about asystole and CPR

    I've always thought it measured the electric impulses from your brain, telling your heart bo beat? Wow, I guess we all learn something new everyday. What about defillibration? What will happen to the reading, both the pulse oximeter or the ECG?

    Mind vs Reality: What is the Technical Term?

    Yes, as Russ has said, it's called Visualization. It's a technique recommended for almost everything (piano recital, performing a 10 meter dive etc). What you mean by the brain not being able to distinguish reality and products of imagination, is actually called 'Schizophrenia'. It's when you...
