Is this used in applied sciences? if not, why?
Can someone explain why gamma radiation is ionizing but neutron radiation is not (or is called indirectly ionizing)?
Various books and sources explain that the particle hitting the atom must bear charge in order to ionize it.
Yet gamma rays don't bear charge.
Then I read this
>Even though they bear no charge, gamma rays are able to produce ionization as they pass through matter. (http://www.chem.wisc.edu/deptfiles/genchem/sstutorial/Text4/Tx45/tx45.html)
But Wikipedia states that sometimes neutrons are more penetrating than gamma...

I'm going to guess that neutrons with high energy arent going fast enough to effect the energy of electrons, but because they are so much heavier they penetrate and still can have more energy than electrons
It needs one charge or another to take part in the atom dance otherwise it just drops 420 blaze it
More penetrating = less ionising bruh
Because λ=h/p, and neutrons are so massive, p is large and λ is small. Less chance for collision. This doesnt feel very legit someone correct if I'm wrong.
What is the likelihood that if extraterrestrials invade that they'd be massive smartasses who fuck with us while they attack?
It might not be unlikely at all, considering the premise. There's not really any practical reasons for a ground invasion that make sense so you're left with them being ultra sadistic, ultra compassionate, ultra something.
Does being a good scientist mean, giving up everything else?
Whats the physics/science behind karate men being able to break multiple blocks of wood or cinderblocks with one strike of their palm? Like seriously wtf, why arent we weaponizing this?
It's way simpler than you are thinking. As far as breaking wood. It is mostly a trick. You hit it along the grain and it breaks pretty easy. Try hitting it across the grain one time and break your hand.
Some karate experts do have a tremendous amount of strength and this is due to how they use their body as a whip. Their hand or foot is then travelling with great force. I believe Bruce Lee was recorded as having a 5,000 pound force punch.
What am I doing? Someone tell me if this is something that exists already because I am just screwing around here wasting my time and this interests me for fuck knows why and if some math dude already has a name for this shit I would just like to go simply look at it instead of writing all this junk down for fun.
but to answer your question, a whole number greater than 1 that is only divisible by 1 and itself. Has no other factors.
Google is a beautiful thing, I'm sure you know that as a chem major.
what are your thoughts on the golden record? Will it ever reach anything/anyone? Should we have changed what we put on it?
We certainly shouldn't have put a map back to our solar system. Seriously, why would anyone leave their address and directions to their house out for anyone to find?
At least it will lose its accuracy over time.
>We certainly shouldn't have put a map back to our solar system
This means absolutely nothing. The chances of an intelligent alien race accidentally stumbling upon the probe in interstellar space is impossible.
And if by some miraculous means they did capture it, they most likely already have the ability to detect our system so it makes it pointless anyway.
What are your thoughts on saturated fat /sci/? Is it harmful?
This guy got into MIT at 15 just by taking online courses. What's your excuse?
Is now the time to get into fields which will play a role in advancing commercial space exploration and colonization?
Will the industry be starting to advance rapidly in a few decades from now if not taking off (excuse the pun)?
My interest is in planetary geology, and I can see this being one of the crucial fields. But if the industry doesn't start to take off then going into planetary geology could be a major dead end.
Is there a scientific reason for why goat eyes have weird rectangular pupils?
Yes, I posted a link to some discussion on that matter in one of your earlier threads.
Given that, and the rampant goat-posting, I doubt the sincerity of your query; you're an obvious shit-poster.
I roll two dice n times and sum all of them together. What is the probability that the sum is divisible by 7?
What is the limit of the probability as n approaches infinity?
If youre rolling TWO dice n number of times youre always going to get at least 2 as the sum. The further you roll and the more n times you roll these numbers will become greater and the probability increases that the sum will be divisible by 7. In other words using probability, the probability will be n*pi/(2n^2)*7 that its divisible by 7. As the limit of the probability as n approaches infinity also approaches infinity. Do your homework pleb.
I had seen a thread on here recently about what will civilization (or the lack thereof) be like in 25 years, it was a pretty good read so lets get some IQ's in here and tell me (normal QI) what will we become in 50 years? (Moore's Law, colonizing Mars vs. Venus, extinction level events)
This will happen in every thread
>What happens in 50 years
Literally everything will be the same but smaller and more expensive.
>colonizing Mars vs. Venus
I dont think anyone who has half a brain would consider colonizing Venus over Mars. Get fucking real.
>extinction level events
I doubt a giant impact will happen or a nuclear winter in the next 50 years. Climate change isn't an extinction event, we just won't live on the surface anymore.
OK anons, revving this bad boy up in a new form. I've been influenced into the opinion lately that you shouldn't draw the whole organic/inorganic line across chemistry, and so I think instead of having /ogen/, we should have /syngen/ . So here we go.
First, I'm getting the textbook recommendations out of the way:
Clayden, Wade, Klein, Bruice. Fleming's "Frontier Orbitals" is great, and Silverstein's "spectrometric identification of organic compounds" is the dankest

Here's something to start us off -- propose a mechanism.
On a side note, does anyone have tips for columning tiny samples? I'm talking like 60mg here. I've walked past labs and saw people doing columns in glass pipettes. What's up with that? Are those columns or just plugs?
Oh yeah and I'm hoping people recommend some inorganic books, and also maybe give me a place to pull some problems like the organic mechanism ones.
I think I've seen this problem before.
IMO 60 mg is too much for a pipette column but it depends on how much garbage there is to remove and the differences in Rfs.
I used to routinely put ~25 mg of product on a column 1 cm wide and 5 cm tall and didn't have problems finding or collecting it.
