Well would you look at that indeed! I argued for a loss of 348-282=66 sec in Merlin, and said that Raptor would be somewhat less of a difference but not much, as "chamber pressure has a positive but fairly weak correlation with ISP". You said 384 - "360-370" = 14-24 sec difference.

And the reality is... drumroll... the envelope please...

384-334 = 50 sec

I hope this has been a learning experience for you.

Companies have been doing health initiatives like this for years.

If Aetna really wanted to do a "health initiative", maybe they could start by actually paying health insurance claims instead of fucking people around. They're famous for trying to "run out the clock" on sick people,. hoping they'll die before a claim is approved.

I train brazillian Jui Jitsu. I wanted to wear a fitness tracker to figure out how much work I do in a session because they are very intense, the warm-ups are what most fitness places call a 'work-out'. You can wear them in the warm up however the trouble with them is they get torn off when you fight and they *can't* track the amount of work I am doing.

If you train Jui Jitsu, why do you feel the need to quantify the amount of work you're doing? It's like needing a special device to tell you how much fun you're having at a party.

If you need to quantify your martial arts workouts, you're missing the point of martial arts, no? Maybe I'm wrong and am just not hip with the kids these days, who seem to seek numerical validation for everything they do in the form of "likes" and "favs" and "retweets".

In thirty years of martial arts training, study and instruction, it has never occurred to me that knowing the number of calories I'm burning will be in any way enlightening. But then, I'm not really part of Apple's target demographic.

No, I don't think the CELL system would have handled the increased load unless the venue was used often at this capacity...

Hofstra has been used for this purpose before, and for much bigger conferences than the measly 1000 people in the hall last night.

They charged $200/head for their wi-fi hotspot. $200,000 can pay for a lot of bandwidth for a 90 minute event.

This is not correct. Juno is planned to do some limited observation/a> of the Galilean moons. It's a side mission, not central to it's focus (and Juno is anything but optimized for it), but it's one of those cases where, if you're there and you have the hardware...

Concerning Europa (remember that this was before the recent news):

The most significant opportunity for Juno to do Europa science would be to follow up on the plumes possibly detected by Hubble Space Telescope. Confirming Hubble's detection would be very scientifically valuable. Any information on the source location would be valuable. This science goal just may not be possible with the large distances from Juno to Europa, but we will look.

JunoCam or ASC can only detect plumes if they contain fine particles. The Hubble discovery (if real) only shows the presence of water vapor. We can predict by analogy to Enceladus that water vapor plumes will also contain particles. However, it is important to remember that the Hubble discovery was of gas, not particles. If the putative Europa plumes are Enceladus-like and do contain particles, they would not be as tall as Enceladus', because of Europa's higher gravity. Scaling for Europa’s gravity gives a maximum plume height of under 140 kilometers. To detect plumes, we need at least two pixels, so the image spatial scale would need to be better than 70 kilometers, at a relatively high phase angle where the particles would forward-scatter light to JunoCam and ASC.

To achieve resolutions better than 70 kilometers per pixel, UVS needs to be within 40,000 kilometers of Europa; JunoCam, 100,000 kilometers; and ASC, 170,000 kilometers. For the cameras, given the low expected height of the plumes, there is not much flexibility.

There are just four orbits that have Europa flybys that are closer than 300,000 km. Juno reaches the best available geometry in September 2017 as the rotation of the line of apsides brings Juno’s orbit close to Europa’s orbit:

2017-03-08 253,118 km
2017-09-19 264,043 km
2017-10-03 92,267 km
2017-10-17 204,654 km

It's pretty limited what you can gather from individual grains captured at hypersonic velocities and analyzed with spacecraft-sized instruments. Certainly there was no "clear evidence of life" from Enceladus - although it showed us some very promising things about the potential habitability of its oceans.

Personally, I'm not a believer in the theory that wherever there's liquid water, there's life. First off, it'd make the Fermi paradox even worse, as water is bloody everywhere. Secondly, I think it's incredibly naive. The argument goes, wherever we find water on Earth, we find life, and whereever we don't, we don't, so we should expect that with the universe. But that says nothing about how life came about. Sure, LAWKI requires hydrogen, and water is the most convenient source of hydrogen, so obviously that's going to form the boundaries of where life has spread to. But where it's spread to says nothing about where it originated, or what it looked like when it did. We have no reason to think that the entire wet surface of Earth just spontaneously erupted into life; we certainly don't see anything resembling this in laboratory abiogenesis experiments. So what were the specific conditions that brought life about? I think it's a safe bet that they were rare. Quite likely no longer present on Earth, as Earth was a radically different place back then. And quite possibly rare in the universe as a whole. Little bursts of luck separated by great relativistic distances.

Indeed, bodies like Europa (and the many other bodies confirmed to or believed to have subsurface water in our solar system) should help answer these questions. I'm also exceedingly curious about what's gone on with alternative solvents and polymeric compounds, such as at the surface of Titan (I find the cyanide chemistry there fascinating, it seems to be extremely flexible).

The trolls appear. The reason the U.S. exists is because it got tired of being England's whipping boy and paying tax after tax but getting nothing in return.

The colonies then pursued peaceful means by sending protest letter after protest letter to the King outlining the usurpations they were enduring and even suggested remedies.

In the end the King ignored all peaceful attempts at resolving the underlying issues. Only then did the colonists take up arms against those they perceived as oppressors.

Hardly ignoring the law.

Hillary is not the "true believer", her fans are are. She merely exploits the sentiment. Same goes for Trump, but "trickle down" and the Clinton/Wall Street bubble of the 90s are what kept him rich, so for sure he's not against it. He will do very well with another Clinton victory. Trump himself, he looks at the ratings and says, *Mission accomplished! Pay up muthafuckas!* What a masterful job he did.
