What should a freshman CS major like myself be doing this summer? I'm not really sure if I want to do grad school or go into industry but I'm leaning for grad school. Are REU gigs hard to get? Or should I just pester some professors here? Alternatively, I might be able to score a decent paid software engineering internship based on connections.
Ok /sci/ please help me I'm probably retarded. Why does length contract as you approach the speed of light? Everything I'm seeing implies that its simply the fact that simultaneous measurements in one frame are not necessarily the same in the next frame, right? So why then is length contraction not essentially considered an illusion as a result of time dilation? Length isn't actually changing right, so really its just time?
Mail me pls? GGL is great, I don't want to steal your thunder, I'm always open to discuss, are you? Chemlambda is a graph rewrite system (like GGL) with a random algorithm for reductions. Differences: (1) not any rule, but a small specific set of rules (why: because making rules is cheap and the explosion of consequences is huge), I think that by accepting any rule there are very small chances to fall over really interesting ones, have you seen what chemlambda does? (2) the accent is on individual molecules which eventually do the job in a random environment, instead... Comment too long. Click here to view the full text.
So i understand that enzymes lower a substrates required activation energy and allow them to function at a much high rate. My q is there is no free energy. So where does the energy that the enzyme uses to lower the EoA come from and how does an enzyme lower the energy of activation specifically. thanks
>>7710879 It all depends if the reactuon first starts in the presence or absence of oxygen to obtain the energy. If there is a lack of oxygen the energy produced is very low and has the byproduct lactic acid as you know. This energy drives the pathway to begin in zero and first order kinetics. The enzyme uses the energy to quickly break the bonds of a substance. I hope this helps.
>>7710901 that did not help at all. what does areobic or anerobic conditions have to do with enzyme activity? i'm talking about their activity in the context of the human body. We are not talking about gylcogenisis or glyconeogenisis or metabolism. ..
>>7710879 It comes from weak interactions between the enzyme and the substrate, such as Van der waals etc. The activation site on the enzyme provides an ambient that stabilizes, using these interactions, the transition state of the reaction. So the probability of the reaction going from either sides is more balanced, requiring less energy to push the transition state to the products. The key thing is to understand that the enzyme is specific to the transition state, not to the substrate or the product.

None of your bussness.
>>7710743 Just reduce a Glutaric acid into Glutaraldehyde (reversing the step it gives you). Now set glutaraldehyde next to a formaldehyde, and pick the oxygens to subtract that were added via ozonolysis. Don't really feel like drawing it out myself but it shouldn't be hard at all. Then use the IR data to check/add anything necessary.
>>7710502 People tend to be confused by the mathematical usage of "simple" and "trivial", assuming they mean "easy."
"Trivial", for a proof, can mean a few things.
>It is easy >That the premises P "trivially" imply the result, because the result Q is always true regardless of the premises (proving that Q is always true, however, may be very much not easy) >That... Comment too long. Click here to view the full text.
>>7710483 Young Earth, definitely. Flat Earth just doesn't work in terms of physics, and requires the existence of a massive global conspiracy to cover it up; all a Young Earth requires is for God to be a deliberately misleading dick.
I am good at physics but suck at calculus. But this calculus is like a really difficult theory course and not your normal calculus. We do a lot of proofs. I don't know what you mean math but I figure if it was just computation calculus with no proofs then I would do well but as it stands down now I have a much higher mark in my other classes than calculus.
>>7710383 It actually characterizes the functions into certain groups or categories depending on whether you can find elementary antiderivatives for example. It's a very strong theoretical study, at first sight it's obviously dumb just like "straightedge-compass constructions" seems arbitrary and dumb until you use field theory to study it
>>7710383 >Why are these called closed forms: pi, e, sqrt(2), ln(3) Closed form is a hazy definition to begin with in my experience. Generally it refers to elementary functions like Sin[x], Sqrt[x], Exp[x], Log[x] or constants like Pi. I can't tell you why such functions are considered elementary. For example, the error function has a relation to Exp[x] but it is considered special.
