thought I'd ask this now since all the astrophysicists seem to be awake.

When a photon is thought of as a particle, it has mass as far as I recall. But when you think of it as a wave, it goes at light speed (at least in a vacuum). And both must be true at the same time. Right? (??) So surely at light speed, its mass would become infinite?

I heard that the eye of the hurricane is the worst place in the entire storm. Do you know why this is.

Consider the quadratic relation y=2x²+12x+54.

a) Use two different methods to determine the equation in vertex form.

b) Which method(s) enable you to also find points on the graph that are equidistant from the axis of symmetry?

c) Which method reveals the x-intercepts of the graph.

d) If the graph of the relation is not required, is there an advantage to using one method over another? Explain your reasoning.

What if, when we get there, it's boring? I mean, there are buzillions of starts, and we have to blow our entire planet's energy budget for a generation just getting to the nearest one. What if there are no little green men to talk to? After all, we haven't even picked up their TV channels yet.

So what do we think we'll find when we get there? Anything worth the trip? Are there, at least, any planets?

We're off to Alpha Proxima, 4.5 light years away I think. Let's say ten or so years is a reasonable time to get there, so half of light speed is OK. No need for multiple generations or suspended animation, though a good DVD library would help.

(1) Mass - We can't hit infinite mass or we become a black hole. How massy are we? Let's say we started at 100 tonnes. As far as I recall it's 1/(1-u^2/c^2), so our new mass is 133 tonnes. Fine!

(2) Acceleration. We can tolerate 1g, in fact that's extremely comfortable. So we accelerate at 10m/s^2. That takes us a bit less than six months to get to speed. Also fine!

(3) Energy. We need E=1/2 * mass * u^2, which comes to 415,625,000 TWh of energy, which is 30 times the world's annual electricity production.

Ah.

OK, can you fix this?

I live in California and we are in a stage 2 emergency right now. If we reach stage 3 we will start experiencing rolling blackouts...and I really don't want that.

I have my AC on 78 with the "engergy saver" feature turned on, and a fan running. Are there any other little things I could be doing to conserve energy?

Iam battling to find the second derivative using implicit differentiation of the following question:

sqrt(x) + sqrt(y) = 1


I know its an easy question and I know Iam making a mistake somewhere along the line. Please could anyone show me how to do it step by step. Many thanks
