Hi, I'm so tired of hearing people suggest "hurr durr, why don't you put solar panels on your drone/car/whatever, then you don't need energy hurr..."
so here I made some calculations (numbers may be off, I just took the first source I found for everything too lazy to search around for ages).
From a random source I found that the light intensity from the sun is roughly 1300W/m^2
(i.e. 1300 J/(s*m^2) )
Normally solar panels have around 20-40% efficiency but just for the lulz lets assume ours has 100%.

You may be interested to learn there are magical things called batteries that allow energy to be stored rather than used immediately.
>>7755823
Solar power on a drone makes sense since it means the drone can be inert in the field charging up its batteries. I agree that solar cells on a car is pretty daft, but if you can overcome implementation issues I dont think it does any harm.
I get that you're wary of hype, but you come off as being contrarian rather than skeptical.
>>7755823
sure you wont be able to run a car off the solar panels but you extend the range (if the energy gained from having a solar panels is larger than the energy required to carry the panels) and allows you to recharge the batteries for 'free' or away from a charging point.
We are going to play a little game.. if you crack the algorithm to a few select numbers I will reward you.
How did I turn:
24141820291911 into 210323734155?
Don't ask how or what the reward is because you haven't earned it.
>>7755792
There is literally an infinity of algorithms that can do that
>>7755794
Well show me the best one.
>>7755801
Define best.
are there really people who can stay highly focused and study 8 hours straight without getting distracted?
>>7755140
without even checking 4chan once?
apparently not
If you like Science and Logic so much, why are you on 4chan?
>>7755011
Because I'm a jackass.
Nice dubs tho.
>>7755011
Because Aggression is a Bastion of What Betters what one would consider Bullshit

Is there a recommended way to read this while skipping all the dumb filler? I think his main thesis is interesting but I want to get at the actual substance of the argument without sifting through a bunch of fucking proto-reddit memes.
I can't answer your question, but I am curious. What is his main thesis?
>>7754665
>sifting through a bunch of fucking proto-reddit memes.
You people just hate fun.
>>7754665
I'm also wondering this. I started reading this a few years back but eventually got fed up with all the dumb storybook shit between each and every chapter so I put it down and never looked back.
I wonder if it's possible to have a really high iq and be poor at learning physics
>>7754312
no sorry you're just retarded
>>7754312
Yes, I have a genius IQ and I'm poor at learning physics. I always try to study QCD but then I get distracted by more interesting and more intellectually challenging things due to my high IQ.
Which path should I choose Algrebra, Analysis or Geometry?
I'm an undergraduate pure math student
Whichever one you like most
And then you'll realize all math is one and making a choice is silly
Algebra and geometry are the same thing.
Analysis is if you don't like rigid mathematics
>>7754239
I got 40% in grade 10 geometry. If im not good at geo, you arent, so do algebra, because solving for x is fun
The NSA might flag me for this but...
What is DARPA up to right now?
I heard they are already working on neural prosthetics. That they are taking injured Iraq war veterans with brain damage and trying to restore cognitive ability with computer chips.
I really want to go work for DARPA one day but probably will never get the chance, seeing how bad at keeping secrets I am.
Anyway /DARPA/ thread

Why don't you ask them.
I think they are working on ghost in the shell technology by now.
I wonder if they have a cloaking technology program...
Is this thread bumping?
A challenge for you nerds:
Make a meal plan for a day or a week with a $15/day budget that meets every nutritional need.
No vitamin pills, as you can never be sure what's in them, and even if you could be sure, it's been shown that (at least some) vitamins in pills do not have the same effects as vitamins in real foods.
No stupid shit like 'eat 500g seaweed' or 'buy a whole cow and freeze it and slowly consume it over several months' or 'eat goat testicles'
I bet you can't do it
Human breastmilk every day for every meal.
>>7753797
15 dollars a day is a lot lol
canned tuna / whey / chicken / sirloin beef
becel / peanutbutter / olive oil
bread of any kind
1 a day multivitamin + multimineral centrum brand
>>7753797
>$15/day budget
you could do that on 5 a day easily
Is there anything more circular than a circle?
>>7753493
By definition, no.
the anthropic principle
>>7753493
The most circular object in the universe is the typical philosotard's argumentative structure.
Is it possible to breathe without your own heart?

Not doing your homework for you xDDD

now fuck off

What would be the use? To oxygenate blood that isnt circulating? You'd breathe until you were too tired if you werent in shock
Asking the science fags, is it true cigarettes nowadays have way more chemicals in them compared to how they were 50 years ago? I hear this is why many who smoked many years back lived a long life and was less likely to get cancer compared to smokers of nowadays.
Is this theory true?
There i posted it for you faggot
it's likely that people just smoke more nowadays because cigarettes are likely more addictive, I have no idea what I'm talking about someone tell me if I'm right.
>>7750363
It is true , between fire hazard regulations imposed by states (cigarette must self extinguish if not sucked) and the cigarette manufacturer wanting longer shelf life, better nice delivery, and cough suppressant. Cigarettes are much different than they were 50 years ago.

Nic not nice stupid auto correct
Would you give up your relatively high reasoning ability to be happy?
>>7755737
Trump has 156 IQ, seems to have lived a balanced happy life.
why cant I have both too?
>>7755753
>Trump has 156 IQ,
So he just acts and speaks like an idiot?
>>7755753
>why cant I have both too?
Because only .001% of people can have that
1/3
Sup bros.
I'm a biology student, and I fucking hate life, and I mean this literally. I feel like I have looked into the abyss, and the abyss has looked back into me. I fucking hate animals. I hate living systems. I hate diversity. I hate conservation. I hate conservationists. I hate "sustainability". I especially hate vegans.
I actually love biology, I love the study of living systems, but I hate that the science has gotten so convoluted with the activism. Biologists, almost by definition, must be "in favor" of biodiversity,...

When considering enthalpy and entropy (you physics boys know what I'm talking about), there is no way in my opinion to view life as a "good" thing. I almost have the mentality of a comic book supervillian, who wants to "purify" the universe by eliminating all life. But the funny part is that *this is fucking true*. Life is all about reducing the free energy of a system, and of course increasing the entropy of the system, at the selfish expense of lowering/maintaining the entropy of its volume. Any way you slice it, especially in any moral context, is...

Tell me about the plant who's name I typed in the options field.
Who cares about some fucking tropical tree frog that's going to go extinct? WHO CARES?! PRIMATES CREATED PLUTONIUM 238. PRIMATES CREATED THIS SUPER AWESOME NVIDIA GPU I HAVE. Like...the magnificience of primates is...unparalleled. And as a biologist, having this mentality is, in all honestly, detrimental to my future career. In a way, other biologists don't take me seriously. Why should they? They have no obligation to take me seriously even if I, along with many others, are correct in our views. The sun will end most life on Earth in around 1 billion years--not when...
