Would be a pretty bad look for any sitting, former or elected President to not attend the State Funeral for another President.

Interesting timing for the Funeral. I assume they will do it before the inauguration.

To be fair, there's no practical reason for the average high school or college student to understand how Newton improved Kepler's laws of planetary motion (amazingly accurate at solar system scales and beyond), why the ISS is moving at 17,500 mph, the importance of Lagrange Points and why the James Webb scope is orbiting at L2, and reasons for GPS satellite cesium beam clock time corrections per Einstein's relativistic theories, mainly related to time dilation. Physics and some engineering students yes, for students outside those disciplines that knowledge is interesting but unnecessary. Practically, IMO trig by itself is sufficient and useful for life long use. Classical mechanics, calculus or quantum theory, not so much. The OP's statements are correct; yours are not. If you disagree, then your thoughts to reconcile Einsteinian space-time gravity with quantum theory would be very interesting, the Holy Grail "Theory of Everything" in physics. Or, a simpler problem is why it would be so difficult to establish a GPS system orbiting our moon, a NASA thought experiment for many years.

The O2. Gas only brings carbon to the party, your car takes in O2 from the air. Give or take a pure conversion will make 19 lbs of CO2 and some amount of water from the hydrogen in the gas combing with the O2.

It’s significantly more. The whole we burn fossil fuels to charge EVs, while true, is a silly red herring.

Installed 8’ LED shop lights and the least surge blows them out. Maybe I bought crap but they don’t come close to the hours they are supposed to last.


Feels like you wired them wrong if a power surge impacted anything but the transformer. If a power surge blew the transformer, then you for sure bought a crap transformer.

And yet inflation was mostly low and flat up until 1970. It took off starting in 71. What changed? Oh yeah Gold Standard. Before the creation of the Federal Reserve, inflation was virtually nonexistent.


Neither of these statements are factually accurate. I suspect you don’t know why the FED was created if you think the second point is true.

Federal Reserve and then coming off the Gold Standard are what caused this.


The gold standard is to macroeconomic discussions like flat earth is to a physics discussion.

You can buy an 85" UHD TV now for fewer actual dollars than you could buy a decent 25" console TV in 1976. Building material science had changed a lot in the last 50 years you may not have noticed if you haven't dug around in a 1970s house and/or haven't paid attention to modern homes. It is really hard to make and apples to apples comparison between 1976 homes and 2024 homes. A lot of things are better now and a lot of things are worse.



This is known as the Baumol Effect.
quote:

Pull directly from a google search from the last 20+ years Another search said 2.5% over the last 30 years Investopedia also provides numbers since 1929 here you can reference that show it is around 2.5 or less as a baseline.


My question wasn’t how to look up inflation stats, just use FRED for that. I wanted to know what time frame you were using to make that statement.

The reason I asked is if you didn’t include all the years from 1976, and you clearly hadn’t, what years did you use and why did you pick a different time period?

Really your statement read in a vacuum is if inflation remained constant since 1976…which would have actually resulted in the average home prices being around 500k. This is because the average rates of inflation in 1970s and 80s were significantly higher than 2.5%.

So, I was thinking maybe he meant if inflation rates had remained consistent with rates before 1976 vs since 1976.
quote:

*2.43% inflation year over year starting and an average home cost of 43,400 dollars in 1976.



How are you coming up with that rate? Which time frame?

Nope, sadly it’s worse. They are heavily subsidized by the freight railroads too, in that they run for next to nothing.

Imagine being so bad a business model that even with nearly all your fixed operating costs paid for…you still set money on fire like that’s actually your model.
