Anyone here doing anything optics related?

sort of, trying to make a material that exhibits the large photomechanical effect, scrubs CO2 from the atmosphere, clean energy, and maybe cancer too. Oh and it's like gonna be programmable too, so like we could tune it to whatever we want. Or at least that's what we said in the proposal

It is not going well. The project's horribly mismanaged. We haven't heard from our chemist in months, because somebody forgot to pay them. I just found out the other day that the team member who was supposed to be doing quantum chemistry sims to characterize our shit has not done a single one like ever.


But worst of all, I feel like I can actually save the project if I actually worked hard enough and that I'm gonna miss out on the research of a lifetime if it fails. If we can make it work we can actually do some amazing things.

I hate myself for posting on 4chan instead of working on my research.

meant to say cures cancer, but I suppose it could cause cancer too.

take your shitty philosophical arguments from incredulity to >>>/lit/

>>8106979
That is just a thesis stating sentence, an argument would offer justifications for it...

A philosophy class would help you realize that, you insufferable faggot.

the reason for aging is death from external causes .if an organism usually survives X years against predation\other shit its evolutionary pressured into being fertile within that lifespan getting to it as early and for as long as possible .

if an individual survives much longer then that usual lifespan hes in uncharted territory , the 'evolutionary shadow'. basically your ancestors didnt live this long so no natural selection was made against fuckups which occur once someone reaches this age .

this is similar to the reason older parents produce shittier kids , they had less ancestors who 'beta tested' reproduction at that age , so modern practices like having kids later in life increase chances of all sorts of fuckups .

so basically you can think of your genes as including all the evolutionary pressures your ancestors experienced up to the point they reproduced .
a perfect immortal man has no evolutionary advantage over a man that falls apart and dies the moment he turns 20 if both of them reproduce at 19.

this also presents a way to extend human lifespan : have kids later in life . sure you'll have shittier kids buy by having longer selection you produce people that live longer .

Geometry is literally everywhere. Especially in physics. Everything from euclidean geometry and trigonometry to do simple mechanics problems, to hyperbolic geometry in SR, differential geometry in GR & gauge theory, algebraic geometry in string theory, etc.

Should be

Phi^2 + 2phi + 1

What's crazy is we could come up with new ones but companies won't do it because they're too expensive and are worthless within like a year. Still though, I bet a government out there is sitting on an unused one for the "important people" to use if shit goes down.

I'm not even denying manmade climate change, but you're arguing against a strawman.
Global warming is something that can be observed. Human involvement in it is the thing that people are sceptic of.

>>8117253
You are changing the subject. There have clearly been claims that global warming itself is not happening, and that this is just the natural wavering of temperature over centuries.

I love how the most vocal fuckers are constantly conflating different subjects. It's just like anti-evolution switching subject to abiogenesis. I don't care what you believe and am open to discussion, but please keep your topics straight.

>>8117253
No we deny temperature rising too, tons of corruption and modified data has been proved, while the only "real" data we have, satellite data show no rise in temperature in the last 18 years.

The process of mitosis. The fundamental process of asexual reproduction. The scope of mitosis is to segregate the genomic information in two cells. Here we see the chromosomes in red and the microtubules in green. After the chromosome condensation the microtubules organize in a spider like structure. They are ready to pull the DNA at the opposite poles of the cell. Once the chromosomes are separated the cell goes into anaphase then telophase and divides.
