Recrystallized paracetamol from acetone

Sulfur recrystallized from toleuene

Some KMnO4

Benzoic acid

Another run of benzoic acid synth and recrystallization

I don't get it why it's so streched out. Now it certainly isn't as pretty as before.

dude you some kind of freak? wtf.

Now what would make you say such a thing?

come on dude youre creeping me out..

Not OC but still looks cool

Bump

Old picture of my ghetto reflux set-up

Muh makeshift hydrogenation apparatus

It....uh...didnt work

Is that a balloon? Did you just put hydrogen in there?
Also what did you try to hydrogenate?

Bald ass eagle

some mf mallards

if you want pretty pictures of crystals lookup birefringence. Pic related, its a pic I took thru microscope of crystallised BHT

the CDC has a pretty nice collection of bacteria images

enjoy your cacer chemfag

I actually spilt some chromic acid a few weeks ago. Wiped it up and I think a bit got on my finger, so we're probably on with the cancer.

Here's an HE plate cultured with some opportunistic enteric bacteria

Another HE plate with Salmonella

Those yellow/orange colonies mutated to ferment lactose. Kinda spooky

A blurry Mycobacterium culture. Looks like mini string cheese or that crap that clogs up your pores

Staph aureus on a blood agar plate with a novobiocin tablet to determine susceptibility

S. aureus will fuck your shit up look at all that hydrolyzed blood senpai

OP here. These are amazing. On the second picture did the yellow colonies mutate by themself or was it intentional?

this is the picture that appears in "The art of computer programming: bitwise tricks"

I think the title is wrong though, and it's backwards

We think it mutated by itself. There may have been some interaction between the Salmonella and Shigella species on that plate that enabled the lactose fermentation but it's largely a mystery

2016 in a version of Jacob Barnett numbers using lines to represent 2

Biology is fascinating. It's so spontanus and unpredictable. Just wow

this is 2050

I was thinking about this the other day. How do you think he represents 4, or 8, or 16? I think since he rotates the shape 180 degrees whenever multiplying by two, if you want to represent 2*2 you need to move into 3 dimensions, basically a plus sign that comes out of the screen. If you want to represent 8, you need to move up to 4D, and so on. Maybe this is how Barnett visualizes higher dimensions so easily?

It's just pretty

>Jacob Barnett numbers
this shit is just fucking stupid man im sorry

Powers of 2 on this program are just single straight lines. This is just because it allows me to use the same geometry shader for all shapes, and not handle any inconsistencies. What it does is takes 2pi, divides by the number of sides to get an increment, and then iterates through generating points with the given angle.

Ideally, I think it would be best to define all shapes using this algorithm because it is more consistent. One change I might make is have the starting angle be normal to the unit circle, instead of always being 0. It wouldn't even be that hard to implement, I would only have to change the geometry shader.

The only problem is what to do with the first line. I would probably just make it so you can toggle which of the two starting positions you want

I get it user, I am jealous of the kid as well.

nah that's an onion
