I have always been very interested in chemistry and physics, but when I watched this documentary it blew my mind. Even though I didn't understand 100% of the idea, but I was amazed at how small things can have a great impact on massive things. Do you think it's true, or just numerology? Give me your thoughts. Thank you.

with them being made of gas? or are they too dense? but then surely no gas is too dense for an object to pass through, wouldn't that make it solid?

travel through time. I wondered about that, then realized it might be impossible. How and why? The answer will surprise you!


The answer occurred to me from watching the "Back to the Future" trilogy. I already gave too big (of) a hint...

When we configure our wireless router, it asks us to select a power level 1-10. Each of this power level has a mapping to some XX dbm. I need to find out the exact mapping of each of those power levels.

Thanks

⌠ln [(e^3x) – 1] dx
⌡ e^2x

* That's the natural log of the quantity ("e" to the 3x) minus 1 all over "e" to the 2x.

The only hint given was that it's POSSIBLE we will have to use ALL the Integration Techniques we've learned thus far. They are:
1. Regular u-substitution
2. Integration by Parts
3. Trig integrals
4. Partial Fraction Decomposition
5. Using Pythagorean Theorem w/ Right Triangles
6. Completing the square

I started with a regular u-sub. Letting u = e^3x - 1 and du = 3e^3x, but ended up at a dead end. 0_o Any feedback is greatly appreciated. :)

19. Jack wants to buy a two-scoop sundae at Baskin-Robbins. How many choices of flavor combinations
(C) does he have if he is allowed to choose the same flavor twice? Recall that there are 31 flavors in all!
(Chocolate and Vanilla is the same as Vanilla and Chocolate.)

(a) P(31, 2) (b) C(31, 2) (c) C(31, 2) + 31 (d) P(31, 2) + 31 (e) 312 (f) none of the others

I said A because you are selecting and arranging the flavors. The correct answer is C. Please someone explain

20. For two events A and B we are given that Pr[A] = 1/3, Pr[B|A] = 1/2, and Pr[B|A] = 1/5. Find
Pr[B]. (A)
(a) 3/10 (b) 7/10 (c) 7/20 (d) 1/2 (e) 2/5 (f) none of the others

this question the answer is A, i had no idea how to figure this one out
