>CRISPR is all around the research papers, it goes around really rapid with breakthroughs here and there every month

>bionics get more and more cheaper

>NSA wants to rush post-quantum cryptography, for they suspect quantum computation coming within the observable time scale

>the Moore's law doesn't look like it wants to slow down in all the field mentioned before

What will happen in the next 10-15 years? It all looks like upcoming major changes, the way I observe. Was Kurzweil right all the way?

Don't believe /sci/ has no interest in the fancy stuff you see in MIT press releases/Cell/Nature.

Lately, the stuff is getting more and more interesting.

• Arctic Sea Ice Extent
February 2017 sea ice extent was 7.6% below the 1981-2010 average — the smallest February sea ice extent since satellite records began in 1979.
• Antarctic Sea Ice Extent
February 2017 sea ice extent was 24.4% below the 1981-2010 average — the smallest February sea ice extent on record.

Do you have to study all day to get good grades or is calc so easy that you don't need to do anything? One minute /sci/ makes fun of you for saying you had to study your ass off, the next minute they say you're supposed to.

marginally. i fucked off all week and still graduated in the top 50%. some people are smarter than others.

busting your ass to do the best you can will never, ever hurt your chances though. i wonder where i could be if i put more effort in my studies...

Why have I not met any chem majors that love Chemistry?

Because Chemistry is boring. Most people go into it because they're told they'll be the first trillionaire if they find a way to synthesize oil easily

I love Chemistry, I get how some people get scared by brainlet courses but the applications I find from my education is endless, and it makes me wonder from reading a previous thread about premed students going in these programs for money, is there any altruism left in science, is the majority of our generation of new scientists just in it for self gain rather than the benefit of humanity and life as a whole?

How much does GPA matter for going into industry for engineering?
30 posts and 2 images submitted.
>>
4.0
>>
3.9+ plus chad social skills
>>
Depends on your portfolio, and if you have prior experience/internships. If you have an empty workbook and no prior work experience an employer has no choice but to weigh your GPA highly when evaluating you.

Since this is probably your first job, I'd recommend building an expansive and descriptive portfolio of projects which show competency and initiative to go beyond the basics covered in classroom. Preferably nothing too complicated, something you can readily talk about during an interview.

why do men have so much armpit smell? it's the body part where 90% of my body odor comes from. it's sexually unattractive like bad breath.

whats the point?

Because testosterone = more hair growth = more smell

some people like the smell if it's not too rank

It's not, it's sexually attractive.

Right then, since no one is responding I'll bump the thread with my personal idea:
So I'm thinking a kind of backpack-like oversized lightbulb that intakes atmospheric gas through the top and heats it up to a plasma-like state and then expels the plasma to steer the craft and prevent the device from heating to the point that the filament burns out or the user gets burnt.

kilowatts.jpg

So I'm idly sitting here thinking. I argue with my family a lot regarding the electric bill. We use these special soft white LED bulbs that, while they imp and replace 40 watt lights, only consume about 6 watts to produce the same amount of light.

And still, while my family likes leaving the gigantic fucking televisions running while they sleep, they're still absolutely anal regarding switching these rinky dink lights off when you're out of a room.

So I thought about it. Exactly how much would it cost to run a single 6 watt LED bulb, 24/7, for a year?

Well. A watt is a joule per second. There are sixty seconds in a minute, sixty minutes in an hour, twenty four hours in a day, three hundred and sixty five days in a year. Or 31,536,000 seconds.

Times 6, that should be joules consumed in light. Or 189,216,000 joules.

But then I got to kilowatt hours, and don't really get how to reduce this. How many kWh is that? I'm trying to figure out how many kilowatt hours it'd be per light bulb

The entire purpose of this, of course, is just to definitely hand my family the exact amount of money it'd cost per year just to tell them to stop being so fucking ridiculous about leaving the lights on or off.

you could literally go on any website that sells lights and they tell you what the yearly operating cost is based on x amount of hours of usage per day.
>>
>>8767521
6*24*365 = total kwh used in 1 year
multiply result by cost per kwh
>>
>>8767521
you tard, a kWh is literally one thousand kilowatts for an hour. So we go 6W * 1kW/1000W * 365 * 24 h = 52.56 kWh

If you learn how to lucid dream you could probably work problems in your sleep if you really wanted.

I don't know if the dream state is too magical even when lucid for this to work or not but it'd be very interesting to try

>How do I learn math in my sleep /sci/? I can't seem to learn anything during waking hours.
You could do that while lucid dreaming. Having LDs long enough could be difficult though.
Then occurrences or LDs are rare for some people (like me) so you better stop being a lazy bum and start studying like everybody else.

A better question is why don't you have a calculus book to hand him? How did you learn it?
