Hello /sci/ I'm a Senior in High School and I am taking the ACT in december. This will be the first time I have taken this exam and it is of utmost importance that I score a 33, while not hard I would want to know what tips you have before taking the ACT? Also, what did you score on the exam?

33 is really really high. What college do you want to go to? Also, first time in December? That's really late. What highly selective college has applications due that late?
>>
>>7675801

The ACT is really coachable. If you want a good idea of how you'll do, take one of those practice tests in the red ACT book they give you.

If you don't do as well as you'd like, keep taking those tests, and use the answer key to figure out what you need to improve on.

Good luck.

I've read a lot about DNA specific bioweapons over the years. I have no doubt that they are in theory possible, and that people are taking precautions against it. I can find lots of blogs/articles online discussing it in pretty good detail, but when I try and find actual sources on the matter I've sort of hit a brick wall.

Maybe I'm just not hitting that sweet search-term spot, but I can't find anything published that discusses these designer weapons specifically. Any help?

While it is certainly possible, the amount of time, resources, and money involved would be impractical at best.

It would have to target and entire subset of genetic traits as the trigger. It's not feasible to target a specific genotype and with the spread and interbreeding between peoples of all regions it cannot be safely assumed that a trigger sequence wouldn't kill a large percentage of the population. Especially if the disease that has been modified is particularly deadly or virulent.

No, you need to take the hyperbolic inverse Mellin transform, of the intersection, superimposing a supergeometric Riemann sum in dual (complete) Hilbert space, and then take the double reverse Fourier transform of the residue, and finally just dagger the result.

>>7674982
chop it off and weight it, use a hot blade to cauterize the wound instantly and keep the correct amount of blood within the foot.

>>7674982
Your best bet is probably to extrapolate from a volume measurement gotten from dipping in water.
>>
>>7674982
Tourniquet right above where you want to weigh from. Wait until you can't feel your foot, ~2-3 hours. DON'T REMOVE IT. Doing so could be harmful to your health.

Have a hacksaw ready. Saw below the tourniquet. Be sure not to lose too much blood, as it will compromise the accuracy of your measurements. Weigh the foot.

It doesn't get much more precise.

>>7674952
It's almost entirely science fiction at this point, but who knows about down the road.

An individual's neuronal network must first be mapped, and then some rigid way of detecting neuron firing must be accomplished. Once this happens, neuron activity can be represented in binary (fired vs. unfired) or more plausibly but more difficultly, hexadecimal, where several states of the neuron are mapped at once (chemical transmittance, electrical transmittance, etc). Then of course, there'd be the issue...

>>7674952
It won't happen for a very long time.

The ability to map is irrelevant. You need to understand the functionality of the system as a whole, down to intracellular mechanics, and be able to simulate physics with reasonable accuracy. It's not feasible.

It'll also be a clone, or an identical child. Not you.

Please man grow up ;)... It will not be possible.
It's more likely we will extinct within capitalism influence than we'll ever get mind uploading.

You do the time numerically intensive stuff in C/C++, and manage stuff with python. Sometimes you have to use old Fortran libraries, but they are relatively easy to call from C. Real men port old Fortran code, instead of just calling it.

We have the capability to live as long as our brains don't become feeble, potentially 300 years. Morals and ethics are the only thing holding us back. What do you think? Would you make a clone of yourself and have your brain transplanted to it? Is it wrong to you?

Well, a successful brain transplant would be quite the thing to pull off. I don't believe it has been done before. I have a hard time believing all those nerves could be cleanly joined.

I would totally make a clone in a vat and shove my brain in it if I could.

Also shit like Alzheimer's and Parkinson's would quite possibly fuck you up even within your natural lifespan. I don't know where you get your 300 years from.

Yes. Electronics engineering student here. Express the variables in the (4-bit!) equation in a binary table with two of the variables on the vertical axis, and two on the horizontal one. Complete all the cells in the table by referring to the number of the cell, and inserting a one if the cell number is one of the decimals in the given equation. Then group the ones the derive logic equation. Then design the corresponding logic circuit.

My brother is up 1k by pure luck at this game. We are going together this Friday.

The odds of winning a bet on black in American Roulette are (18/38) = 0.47368

The odds of losing 5 in a row are (0.526316)^5 == 0.04038 or 4%.

If I use the Martingale strategy how many spins can I get before my odds dip below 51% chance of walking away with money? Minimum bet is $5. I'm leaving after I lose $155 in a row. Would the odds be cumulative? 4% + 4% + 4%... and so on? I'd make about 13*$5= 65. Is there a better strategy?

$5 + $10 + $20 + $40 + $80 = $155

The only way to win is to not play. Any statistician will tell you that. Also you technically have better odds betting the entire sum the betting small sums.

Look up the strong law of large numbers, any sample you take will eventually approach its average. The average is always in favour of the house so you're almost guaranteed to lose a large sum of that money (if not all.)
>>
>>7674710
Also, I still expect you're going regardless of what I say. So my advice is to bet a smaller number of larger sums. 2-4 is a bad sample, but 35 samples is starting to get closer to its average.
>>
>>7674699
dude... the game is set up by the house so that you CANT use the martingale strategy and gain a statistical advantage.

Would this hint to souls actually existing?
24 replies and 2 images submitted. Click here to view.

This again. You can go ahead and believe your God is hiding in the cracks, but I have to wonder why, if someone is so willing to believe in the soul, they would have to look for it in physical models. Either deterministic explanations of human origin and being have convinced you sufficiently to abandon spiritual models or there is no need to try to explain spirit with physics. This mode of trying to justify spiritual assumptions with scientific uncertainties reeks of the most rhetorical kind of apologism, playing to the aesthetics rather than reason and also seems rather defeatist.

Just grow some balls and say "science will never completely explain human consciousness, no matter how much we understand the body, the inscrutable soul will always be the dominant factor in our behavior" if that's what you believe.

Is it possible to increase your performance on IQ tests? Yes, just study a bunch of them. They tend to repeat a lot of methods.

Is it possible to increase the thing that IQ tests are attempting to measure? Studies suggest not significantly, but there are far better ways to improve the brain than by improving intuitive pattern recognition. Just learn a bunch of things and get comfortable solving a bunch of things and looking at a bunch of things in a bunch of different ways.

IQ is a statistical thing even under the most generous of interpretations. Most intellectually-successful don't even know or care about their IQ, only those with simultaneously massive insecurities and egos do.

What is the most scientifically optimized way to make coffee?

For instance, cold vs hot brewing or espresso based on the solubility profiles of compounds in coffee beans at various temperatures and pressures and their flavor profiles/aromas, different aspects of cultivation such as strain, soil quality, climate, etc, the chemical changes in different grades of roasting and in whether or not they've been swallowed and shit out by that one mammal, and whether you should add your milk sooner or later to keep it hotter.

Not OP, but nice citations you got there buddy. . . .

I myself heard that hitting some coffee beans with a refracted ionized lazer beam in a .4g vacuum was the best way to extract the flavor.

No citations being needed in this thread of course, so my claim has as much merit as yours.
