Actually we haven’t observed a difference between the speed of neutrinos and light, which sets an upper limit on their mass based on the precision of those measurements. The evidence of mass is much weirder, in the observation of neutrino flavor oscillation.

Neutrinos come in 3 flavors: electron, tau, and muon. We’ve observed that the flavor oscillates as a function of time, or equivalently as a function of distance from the neutrino source. The data is quite precise, and is perfectly explained by there being 3 neutrino mass states that are distinct from the flavor state. So a neutrino with a well defined flavor will have a superposition of the 3 mass states, with each flavor corresponding to a different admixture of mass states.

The flavor oscillations allow us to measure the difference in the mass values, but not the absolute masses. Technically it’s possible that the “lightest” neutrino is massless, and the other 2 mass states are nonzero. Without an absolute value for the masses we can’t rule this out.

“Almost massless”. Neutrino masses are so small that they haven’t been measured (yet).

Solar (photovoltaics), wind turbines, and hydroelectric are a few non-steam energy sources in use.

As for theoretical sources, some of the pulsed-power fusion concepts use the electromagnetic pulse from fusion to directly induce electrical power. But none of these have been demonstrated yet.

If you are poor, there are discounts for those with low income who live in the area. There’s also exemptions for people with medical conditions that prevent them from using public transit source.

Street parking in NYC is $9 an hour, and long term parking garages typically charge like $400 per month. $9 per day is nothing in comparison.

Street parking in NYC is $9 an hour, and long term parking garages typically charge like $400 per month. If you’re driving in NYC the $9 per day congestion pricing isn’t going to be the thing that makes it unaffordable.

This is what I do - make a big pot of chili or soup for the week. But I recognize that this might not work for everyone. At my work there’s a conveniently located fridge and microwave, and I can eat in my office with the door shut for a quiet meal. If any of those things weren’t there it might not be worth it.

I also enjoy cooking, and don’t mind spending time making my meal for the week. If the prep work was a real chore then it’d be much more tempting to buy something premade every day.

Historically movies make most of their money at the box office. It’s rare for something to be profitable just from rentals/streaming, and even if it eventually is it will take a long time for the studio to recoup its costs.

Heartbreaking: The Worst Person You Know Just Made a Great Point

(I’ve been getting SOOO much mileage out of this headline over the past few months)

The thing is, many of the people who were hurting economically and wanted Trump to change things are already crediting Trump with fixing the economy. Polling in swing states between October and November showed a huge swing in voters perception of the economy even though nothing actually changed. So I’d argue this is just emotion for a significant fraction of voters.

Dude doesn’t know how umbrellas work, much less any system of government.

You need a particular kind of nuclear reactor to create the enriched uranium

*plutonium. Enriched uranium comes from taking natural uranium and enriching the content of a specific isotope (235U), typically with centrifuges, gaseous diffusion and/or magnetic separation in a synchrotron. The enriched uranium can be used in a weapon, or it can be used as fuel for a nuclear reactor to make 239Pu from 238U.
