>>8986648
id rather have free answer than multiple choice anyday, especially in upper level sciences like that. at least you can bullshit free answer a little bit.

this multiple choice doesnt even have "answer may contain multiple answers" or "B and C, none of the above, all of the above, ect"

So I just watched this and some blokes created a battery that doesn't explode! Among other cool things check out 30mins on. Stab it m, cut it up to shreads and it still works
http://www.pbs.org/wgbh/nova/next/tech/new-damage-proof-battery-has-higher-energy-density-wont-explode/
>The key to the invention is a solid plastic electrolyte, the substance that bridges the gap between the positive and negative electrodes.
>But Zimmerman’s battery can withstand repeated damage without risking explosion or fire. In fact, it can continue to power devices even after most of it has been chopped away.
>Zimmerman’s solid plastic electrolyte prevents the formation of what are known as dendrites, or tendrils of lithium that spread from the electrode through the electrolyte and can cause dangerous short-circuits.
This guys might end up a very rich man

So it either has shittily high internal resistance or so soft it can be cut with a plastic knife?
>>
>>8985940
Watch it.
The individual cell they use is so thin you can cut it with a pair of scissors.
But because there's no liquid or gel inside, cutting it in half doesn't prevent it from working.

Took amphetamine for the first time before learning maths and it's terrific. I don't feel tired, and I've been working for like 7 or 8 hours now, I don't feel bored as I usually do, I stay focused, motivated and can't really get distracted, when I start doing something else for too long I feel urge to get back to maths. Oh god why amphetamine goes up so well with maths

[eqn] \prod_{j=1}^{|x_i|} q_{x_{ij}}(x_{ij}) \ln \prod_{j=1}^{|x_i|} q_{x_{ij}}(x_{ij}) \\

For exactly the same effect as just having a bat in the path of the meteor.

If entropy always increases then why do things naturally move to the most stable energy level? The most stable energy level does not always mean the highest entropy such as how atoms of chlorine will eventually react with atoms of hydrogen to form hydrogen chloride. This hydrogen chloride formed has less entropy than the free hydrogen and chlorine atoms. Another example would be self-organizing units such as crystals. When liquid water loses enough thermal energy through IR emissions, the water molecules will then self-arrange into a hexagonal pattern and thus lowering the entropy. How can this be???

>>8984539
That's not the definition of entropy. You can not give anyone a physical example of entropy in the world. You are not smart.
>>
>>8984539
Entropy is an increase in information, so things can naturally be high entropy and energy stable. Do you understand what an increase in information means here?
>>
>>8984539

If you isolated a bunch of pure hydrogen and pure chlorine in a space together, what would eventually happen?

The funny thing is that this actually works. No guarantees about the surrounding material that wasn't previously radioactive.

do i have klinefelter syndrome?
my thighs are 58cm thick, most of my fat goes to my thighs and ass.

i had my estrogen and testosterone levels cheked.
doctor said no way i have klinefelter so its most likely homrone issue?
i have decent muscles and i have a bit of facial hair/body hair etc.

my estradial levels were 40.
my test was 500.

im a currently around 6kg overweight. even when i was 6kg leaner i remember being miserable at the sight of my unporportionate lower body.

my hips are wide but they arent really problematic. what is problematic is my thick thighs which protrude laterally and my ass.

if i were to get lean to the point of abs, would this problem disapear?
also notice pic related he has somewhat of a pear shaped lower body, am i just being delusional?

If your doctor says you don't have it it means you don't have it.

You just have unfortunate genes and were probably raised on a shitty diet playing video games all day. Blame your parents. It's what I do.

your love handles are made of fat right?

so keep losing fat and they should go away eventually. that's what i'm doing right now

but you gotta keep protein high and lift so you have some muscle and not a skeleton

Central Dogma is high school-tier bullshit which helps freshmen understand how genetic material is transcribed, nothing more. It's worth shit more than simplifying a complex process for brain-dead bio majors.
