hey guys I'm trying to test something with UV sterilization and trying to by a led which puts out 1W of UVC light, I found a 1W UVC led but it says its radiant power is 2-3 mW??? how the fuck is that possible is it measured from a distance or something? LEDs are efficient and i cant imagine these LED's are 0.2-0.3% efficient ? am i retarded please help

Dielectric: lets through magnetism but blocks electricity

Diamagnetic: let's through electricity but blocks magnetism

I posted this yesterday and someone gave me half an answer that seems to be correct but i do not understand how cos2x = u*du. Sorry if this seems incredibly retarded i just took a an intro course in analysis without any skills in calculus before.

Is this going to reverse global warming?

Is air blue? If not then why is the sky blue?

>UGH why do I have to take these english classes when I'm literally studying computer science? Just teach me what I need to know and give me my degree.

That is not the purpose of college/university. If you just want to learn about CS then go to a coding bootcamp. Go find the hundreds of thousands of python tutorials readily available to you right now and get the fuck to it.

Society has no need or interest for the engineer who is unable to apply history, anthropology, english, the arts, etc into their work and understanding of the world. If you truly are unable to understand how any of the humanities could possibly apply to engineering then you are severely mentally retarded and should just quit while you are ahead.

Does anybody else notice that caffeine or nicotine affects them in a weird way?

I was suspecting I have IBS until I stopped smoking and all my symptoms went away (very frequent loose stools and stomach pains). Relapsing made them come back. All my friends smoke and they don’t have any of these issues.

Drinking anything with caffeine can make me have episodes where I get dizzy and feel like I’m going to pass out if I stand up too fast, after sitting or lying down (is this orthostatic hypotension?). It happens all the time in summer/hot weather.
I also have episodes of sudden weakness and shakiness where I have to eat something or feel like I’m going to faint (it goes away immediately after I eat).

Why does nobody else have these symptoms? Do I have some kind of intolerance to stimulants or something?

What’s causing this in men? Is it really the water?

what are some good ones with insanely mind blowing mathematics
