Comment That's not how science works (Score 5, Interesting) 141

Nothing has been proven. Scientists have long had a theory about how the Sun powers itself. That theory can be used to make predictions, such as the type of neutrinos that we should expect to see emanating from the Sun. An experiment was devised to test such a prediction, the hypothesis being that this type of neutrinos is being produced and thus will be detected. Having performed the experiment, we see that the results match what we expected, validating the hypothesis. This is important and significant, and it provides further evidence suggesting the widely accepted theory is accurate, but it does not -- nor can it -- constitute a proof.

The other interesting result would be if the expected neutrino type was not detected by this experiment, invalidating the hypothesis. This would raise further questions such as: is there some other mechanism powering the Sun? Is there something deficient in our understanding of neutrinos that prevented us from detecting them despite them being there? Was there an error in the test setup (i.e. is it repeatable by other parties)?

Using your number of 0.001% probability of this crash being something technical, and my estimated value of MH370 of $2.6B, then $26,000. The 777 has a lot of flight hours; if there's a technical problem with it, its a corner-case quirk, not a fundamental design issue. Maybe it doesn't sit well with you, but it is not reasonable to expect 100% safety from any system -- it would be prohibitively expensive.

You are of course correct for the initial search, but at some point you hit diminishing returns. Even if the failure were a technical one, the value of locating the wreck and determining the cause is likely of limited value. There are only so many systems that can fail, and we already do thorough failure modes analyses when designing aircraft. That's why flying is so safe these days.

The 777 has a pretty good track record with 1,212 units built and five hull losses, only two of which were due to failure of flight systems. If the hull cost $261.5M and you estimate the value of a human life $10M, then the MH370 incident had a base cost of around $2.6B. If you only had one failure out of 1,212 hulls, that suggests you'd be willing to spend 0.08% or ~$2.1M to make sure it doesn't happen again.

This is just one formulation of the cost/benefit and of course excludes some important factors like the public relations cost to MA and airlines in general, but hopefully it illustrates that there's a bound on how much we should reasonably be expected to invest in understanding the events of the incident, and that it is not an absurdly high value.

As Jim Lovell put it:

From now on we'll live in a world where man has walked on the Moon. It's not a miracle, we just decided to go.

There seems to be this perception that space travel is this incredible thing. It is awesome for sure, but it is fully within our grasp to do with as we please. One of my favourite arguments against the conspiracy theorists goes: if NASA were willing to fake the Moon landing, they would have done something else by now.

Let's reach for the stars again!

Further, this is a high-technology field in which India can excel and become a prominent provider. This brings national prestige, foreign investment and support, provides (some) high-value jobs, and fosters better education. No, it's not going to solve India's problems over night, but it can help.

It really depends what your target inclination is. In general for a non-polar orbit, you want a launch complex with a latitude close to that inclination to minimize plane changes. This is why the ISS is at 51.65 degrees, to make it "easily" accessible from Baikonur. So yes, Sriharikota's proximity to the equator will be beneficial for low-inclination (near-equatorial) launches.

This particular launch, however, was to a sun-synchronous polar orbit. Your launch complex's latitude is much less important when launching to a polar orbit.

Unfortunately, since fusion would be an incredibly revolutionary technology, there is a tremendous amount of money to be gained by being "first to the post". Any investor with money already in one technology will push hard for only that technology to be funded, at the expense of all other lines of research. Fusion research is sadly driven by economic politics.

As a bicyclist you (should) pay very close attention to what's going on in the right turn lane, are they slowing down? Have they seen me? *CAN* they see me? And trust me, I assume that all drivers are idiots playing on their phone will trying to eat a sandwich - having a indication that the driver turning right is absolutely blind and oblivious to my presence just means I can react a second earlier.

Perfect! Since they are playing on their phone, even if their mirrors were intact, they would not be looking at them. Since your assumption of the driver's habits is the conservative one, it doesn't matter whether their mirror is a mirror, a camera, or a shattered piece of useless plastic.
