The part between the corners of the image. It's white and has grey and green blobs on it. You can't miss it.

Same. Arizona's great with the flavors they have, but they don't have a peach tea, which is my go-to if I want iced tea.

Both.

Tolkien constructed an actual language for use in his works, and the gibberish you see on the keyboard is that language.

Their logic:

If something is clear, it is easily understood. Thus, "clearly don't understand" is a contradiction in terms, making it an oxymoron.

On a rational level, I agree with this approach, for people who can do it. It doesn't work for me I practice, though, because breaking a 35 year habit takes effort and focus, and I just don't care enough about the subject to want to worry about it.

So do the people who say "check and mate."

That seems fine to me. I've heard "check and mate" a bunch, so this isn't too much of a stretch for me.

Happy I could help. =)

Well, think about it.

WiFi is electromagnetic radiation, and penetrates walls. The standard frequency is 5 GHz. With harmonics, we should expect similar behavior from wavelengths that are some whole-number multiple of this frequency.

There are multiple such frequencies within the visible light spectrum, such as 500 THz (orange), but visible light doesn't usually penetrate walls, it's instead reflected or absorbed.

On the other end, we have X-rays, which are in the range of 3×10^(16) - 3×10^(19) Hz, which are used medically to see into the human body. There are likewise whole-number divisors, such as 200, which put a potential fundamental at around 600 THz (green). Yet, we generally can't see through people using normal light. That's why we use X-rays.

Now, this is all well and good, but it's all purely academic, because the reason why you can't use your infrared sensors to detect the color blue or purple is because the infrared sensors aren't sensitive in that frequency, the same reason why you can't use your blue cones to detect infrared.

Ah. That makes sense. Something about the harmonics, though:

Sound generates those harmonics because it's physically vibrating sensors in our ear, so we get a 1 to 1 translation of the waveform. Light doesn't, because it's received by 4 different sensors that are sensitive at different ranges and in different phases. The reason we don't experience "blueness" in the infrared spectrum is because our infrared sensors don't know what "blue" is.

I think what happened is Musk wanted to change the signage, and gave them 2 days to do it. While they were working on it, the cops showed up and stopped them because no permits, so they put the original signage back. They report back to the Chief Twit, and he's just like, "All I'm hearing is you have 4 hours to go and my sign isn't up yet."
