To the posters commenting on how amazing it is Americans are wowed by the obvious: there’s an entire electric train network called BART throughout the land surrounding this small peninsula run of Caltrain. And it’s been running since the 60s so it’s not really new to us. It’s also noisy as shit because the wheels are dumb. But it’s still fast.

Go to Turlock, CA.

Read Wikipedia, his father was an attorney for the oil tycoon J Paul Getty and administrator of the Getty family trust. They go deep into money.

You using a different kind of sumac than the rest of us? https://en.wikipedia.org/wiki/Sumac#In_food

It’s for a 3/4 cup serving which doesn’t seem all that unreasonable.

Paper lets the flour breathe, releasing moisture. The grain isn’t 100% when milled and the milling process generates significant heat (mill some grain at home with a motorized mill and see). Warmth + moisture + hermetically sealed plastic smells like a nice way to grow some fungus.

Edit: isn’t 100% dry when milled.

I get that people like to be stubborn about this but there are very real and intuitive reasons that decimals don’t make sense everywhere. Consider how intuitive telling time using “kiloseconds” and decimals might be.

The right tool needs to be used for the right job. I am a scientist. In the lab, metric is fantastic as it allows for precision recording and I don’t care about intuition.

It’s not a point of pride to use one system over another. For example, in America we use both systems in the right contexts. I am happily able to fluidly switch between what’s most appropriate for the situation. I get that context/code switching is generally difficult but I think it’s an overall value add.

If you don’t fight it and accept that imperial is designed with base 12 and not base 10, everything makes more sense. Measurements across all of imperial are to be cut into 12, 6, 4, 3, or 2.

Sometime base 12 works really nicely, especially outside of a lab, when you want to be able to have as many options for division easily as possible.

Do you have an easily digestible source so I can stick this in the face of conservatives with classic talking points?

No, the analogy is more that the oscillations are themselves the particles.

The addition of energy into a system would be this hand push. The fact that the particles themselves exist means that they are oscillations in this mesh (with some energy/frequency). Interactions with other particles can add or remove energy.

Definitely these canvas metaphor are just conveniences. Also, I got it from Zee’s “Quantum Field Theory in a Nutshell” which is a standard graduate or advanced undergrad level book on QFT.

Special relativity definitely overlaps with quantum mechanics and that overlap forms the basis of the math used at collider experiments like those at the LHC. Special relativity is simple with 2 rules that let you derive all the equations: 1) no universal reference frames 2) speed of light is constant.

You’re probably thinking about general relativity which defines gravity through the curvature of space time.

If you think about quantum mechanics existing on some “canvas”, that might look like an interlocking mesh of springs (like something under a bed or cot). You could take your hand and bounces it up and down on this mesh, adding oscillations and creating standing waves in the grid. These oscillations would be different particles (electrons, protons) each with their own characteristic frequency of oscillations. If you add energy to the bed of springs, you can “pop” particles into existence. All these particles actually are are just excitations of the mesh/canvas. As of yet, there’s been no way to define or find the gravity particle on this canvas, so right now the canvas of space time and the canvas of quantum mechanics are two distinct “things”.

I understand your second concern but your first is just wrong. The car only requires a payment for subscription to enable data services like cloud music and the navigation satellite maps are gated behind that. The navigation still works as normal without subscription otherwise but will only show a simple map without textures.
