I doubt your laptop really draws 65 watt's though. Seems a bit too much for a portable running on battery power.

No they did not find that vitamins are beneficial to memory! What they found is that people who have better memory also had more vitamins.

Let's not multiply entities beyond necessity here.

High blood pressure is only bad as it potentially leads to heart attacks, strokes, etc, not on its own (you cannot even feel it usually). However coffee consumption appears to have a protective effect on the cardiovascular systems.

Well, their budget is larger than that of the National Science Foundation. If that is not obscene, I do not know what is.

$7.85 billion is the budget, not the budget increase.

That is more or less along the lines of what I have seen. There is some evidence that it is beneficial in several ways, and very little indication that it may be harmful.

Even if that is true, there is no reason to think that addition is bad per se, as long as there are not negative health or social effects associated to it.

You are off by two orders of magnitude. This 6-cell battery is approximately 55Wh and is rated for 8 hours. Thus a 1600wh battery is enough to run your laptop for about 30 times as much, which is 240 continuous hours. That's 10 days.

What is the evidence for coffee being bad? From what I've read coffee is likely to be healthful.

It is quite sad how few people could do these simple ballpark estimates... I teach CS and half of my students do not know that 2^10 \approx 1000.

As a Ph.D. in physics you should have realized that there was only one answer which looked about right in magnitude :)

Everything else was way smaller or way larger.

From the article:
Today's bombs are smaller but more precise, reducing the amount of collateral damage, Kristensen said.

Amusing, considering that he is talking about bombs tens of thousand times more powerful than the largest non-nuclear munitions.

Depends on your field of study/institution. Our Ph.D. students (CS) make slightly more than $2k/month. Health insurance is also quite heavily subsidized (at least a few k/year). Don't remember the exact amount of tuition, somewhere between $10k and $20k.

I do not see a connection between a Mars station and an interstellar mission. Mars mission is certainly possible, although hugely expensive, with scaled up existing technology (after all we have sent a number of robots there). For interstellar flight we need something radically different.
You cannot get to the moon by building a very high tower.
