Are you asking if the pictured type would be possible?

>>7961885
Yes

probably

Wiener?

>log(x^2) is not always equal to 2log(x)
This can't be true. There's no value for x to make this statement true.

>>7961486
SEARCH UP PROPERTIES OF LOGS AND DO THE SHIT YOURSELF

If you want all the neat exponentiation/logarithm rules to stay in effect, try to keep numbers involved non-negative. Once you consider all reals as bases/exponents/powers, many if not most neat rules will stop being true (and you will need complex numbers too).

Thorium is a meme. Uranium succc xD!!

>Opting for the most easily weaponized energy source possible
Isn't /sci/ supposed to be smart or is that a meme too

I'll tell you all about it when I see you again.

99.9%

>>7957285
Yes, because you can get good with practice

>>7957291
oh look this meme again

>>7957297
Oh look someone who's never practiced again

our body uses enzymes - shit that puts chemists to shame.

In some of the cycling forums, I have read food calories to work calories is 15-25 percent efficiency. I am in mobile....Check Google.

>>7962773
all i can seem to find on google is calorie calculators and shit about losing weight... Dont suppose anybody knows of any real papers or journals or anything on the subject?

>>7962165
Not sure what your doing

Check out generalized coordinates?

Fuck. Maybe it's one of those thoughts that are too abstract that I can't express it. It's annoying the fuck out of me

How high are you right now?

Small inductors will give you large ripple voltages, which will affect the signal.

Large inductors are expensive.

>>7962178
What causes the ripple?

>>7962265
The small induction.

I concur. This is going to go into /x/ dream thread realms but as Mr Zappa said, who gives a fuck anyway. Many years ago I had a dream and all I remember of it was the waking up process of my mind returning from where it had been. I knew I had been aware of, and in, a different dimension. Now I'm not talking about the usual astral projection stuff, floating around some other plane but basically still with a 3D view of things. I mean another dimension in a geometric sense. I was aware that my mind had been functioning in this vastly different way, and all I could perceive was the shutting down of that 'shape' as I returned to waking consciousness. I could feel my mind shutting down part of it's function to return to the physical world. Trying to hold on to the experience was like trying to touch the ceiling when it's out of reach, while shrinking in height.

I've since been in some pleasant states in meditation, quite expansive and definitely they were different aspects or levels of consciousness, but never anything like this dream. It was the most different, unexpected and unusual mental experience I've ever had.

I've no idea if any of this has any practical value. I don't know where I went in that experience, or why, and don't know if I'll ever go back there. It just seemed I was shown a glimpse of something. Maybe as a reminder that what I like to think of as my mind or my identity isn't so 3D after all.

OK science fags, have at it if ye will. In b4 lame 'dreams aren't real' comments.

Brains are incredible, this is similar to some of the effects psychedelics have. For example, LSD changes the way certain neuro-receptors bind to neurons in the brain. This changes the way the brain sends signals, essentially changing the wiring that makes up who you are. The reason people see fractals is that the neuroreceptors in the visual cortex are firing in entirely new and different ways.

With psychedelics and dreams like yours, you can literally experience what it is like to be an alien, with a completely different mental circuitry.

>Plato's "The Cave" is an allegory about how people imprisoned in a firelit cave for their entire life seeing would see the shadows of objects projected on the wall as reality

That isn't what the allegory is about: that's how it's expressed. The purpose of his allegory was to demonstrate the effect of philosophy on the human mind (at least how Plato saw it), and especially to draw attention to the persecution of philosophers (read: Socrates) by a government.

Plato's theory of forms is not the same thing as field theory.

Just trying to get opinions, dude.

I'd say about 7. Maybe a bit more

You'd have to calculate the integral, multiply that by 1/2 * bh (area of a triangle) and multiply again by the volume of a hexagonal figure.

>>7960923
yeah but what hexagonal figure

jump from a plane, you will experience everything you need to know

For every bullshit equation you can't understand thereis an geometric representation to get it on sight.

>>7960324

For many NP problems, deciding a solution is the process that's NP. Checking a solution is usually P. An example is the knapsack problem, that is, optimizing for maximun value the load in a container given weight and value of all items and a max weight. Its very easy to check if something is a solution is valid (sum weights. Is it over the max?), but not so much to find that solution.

>>7959724

Find the roots to some polynomial like [math]3x^13 - \dfrac{1}{5}x^7 - 2x^2 + x^2 = 0[/math]; the actual problem will take a relatively long time to compute compared to checking the solution (i.e. plug in the presumed solution, is the number 0 or not? quick and easy).

>>7959874

Whoops, meant [math]x^{13}[/math]. Anyway that's just a example of something ridiculous that will take a long time to solve.

My first year out of undergrad (back around 2011 - 2012) I had a few temp jobs in CROs and small biotech firms. What's up?

>>7960592
Not OP, but do you have any advice on what you did well or what you would do differently? Specifically I'm a chemistry major graduating in a month.

>>7959625
My friend works in biomedical research. His company is working on cancer research.

From what I gather he spends a lot of his time cataloging genetic information, taking and analyzing samples and killing lab rats, either once they get too sick or the experiment is concluded.
