Student Photographer Threatened With Suspension For Sports Photos 355

A few days ago he was summoned to the principal's office and threatened with a suspension and 'reporting to the IRS' if he didn't take those 4000 photos down. Reportedly, the principal's rationale was that the school has copyright on the images and not him.

I'd argue you are going to need a heck of a lot more rocket fuel for deceleration than the mass a parachute system would require.

I'm not so sure of that. But I'm not an expert. Most of what I (think I) know about space I learned by reading through long discussions on the Internet.

In this case I am thinking back to discussions of SSTO craft and whether or not wings make sense; the experts all agreed that it would be better to land as a rocket than add extra mass to the system. And the key is that the thing lands almost empty... when it's taking off it's boosting itself full of fuel plus whatever upper stage(s) are in use; when it's landing it's just decelerating its own empty weight.

Which of these strategies do you choose:
a) Attach a parachute to the nose and let basic physics work.
b) Try to balance it atop rocket engines firing from the bottom.

I realize you were going for humor (and got it; congratulations on being moderated +5 Funny). But here's a serious answer.

It depends on what you are trying to accomplish:

If your top priority is to save the rocket stage, then you pursue an engineering strategy that has the best chance of saving the rocket booster. Maybe that means a parachute system; I don't know.

But a parachute system adds mass and complexity. It becomes another critical system ("if the parachute fails, we lose the rocket stage"). The rocket stage needs functioning rocket engines, so landing on the rocket engines is another use for those engines rather than a new system with a single purpose. All else being equal, the simpler design with fewer systems is more likely to succeed in its tasks.

If you add a few hundred kilograms of parachute system mass, that's going to mean the booster can push less mass to orbit. I'd guess that the loss factor is higher than 1... that each additional kilogram of non-fuel mass on the booster reduces the to-orbit capacity by more than one kilogram. But ask a physics expert for the actual numbers.

Note that new software to make the booster land on its engines does not add mass to the booster.

So I'd say that if your top priority is to efficiently deliver stuff to orbit, the parachute system is right out and the clear engineering decision is (b).

It was tried for a while, the 0 dollar wage. It was called slavery, and it DID work. The plantation owners were the wealthiest humans to ever walk the planet. Still might have been, adjusted for inflation. A great success. Those owners would have bought the world up with their wealth, bit by bit, had slavery not been sort-of stopped. Of course, normal non-slave humans were competing against free labor, and so barely got by, with lousy schools and dirt roads and abysmal ignorance that lasts to this day. We paid a lot for that free labor, didn't we? A truly "free" market - once side got their goods for free.

People were paid 18/hour in 1966 to work like a dog at McDonald's (you've never worked a restaurant chain job, I see). And the corporation grew into fantastically profitable giant. Seemed to work.

And people who get paid minimum wage don't get forty hour work weeks. They usually are capped at 18-29 hours, to avoid full-time employee status. And the work hours are jangled weekly so they can't get second jobs. Fun!

You're not everyone. And you've no imagination when it comes to life's little snafus. I take it life has treated you well. You've never really been too ill, or blacklisted, or locked into a bad situation because of family issues, or been unable to find employment because of past accusations or convictions, or had a nervous breakdown, or been hit by a car and been unable to function, or been employed in an industry that was gutted for profits.

And no, you've not seen the minimum wage jacked over the years. It was down to 40% of its original value even after all the "jacks", until finally someone performed arithmetic and found it started life at $18 an hour.

Even with a poverty minimum wage, corporations were getting workers for no pay whatsoever - interns - with the promise that if they slave now, someone would smile on them someday and hire them. This is what happens when there are no real laws. After a time, people will be paying businesses to hire them for nothing - logical, same reason. And it is happening overseas - H1B and other workers are paying for the priviledge of not being paid much, or at all, when they bribe recruiting companies.

Austerity failed. Give up. And there is no inflation anywhere that didn't adopt the notion.
The minimum wage was about 18/hour in 1966, and the republic did not fall. Some inflation took off later, but that was Vietnam and OPEC which blew our heads off.
It is possible to pay a decent wage and survive as a business - if you don't demand infinitely growing profits. Inflation and profit slowing is the bugaboo of the wealthy, not the giant group of the people known as the nation. Germany kept its decent paying jobs, and is one of the powerhouses of the planet. They didn't worship corporate profit increases over all else. Balance is the key.

Don't hit the keys so hard, it hurts.
