It's because the wavelength and frequency are inversely related. When the wavelength is low and the frequency is high, the wavelength is also moving very slowly, compared to the frequency which is moving very quickly. Since the frequency is changing so quickly, the power-per-unit-frequency is lower at higher frequencies, and higher at lower frequencies (at least relative to the power-per-unit-wavelength).

Let me try and use a car analogy:

You're driving home through Wisconsin, and you live on the border between Wisconsin and Minnesota. The mile markers on the road decrease as you go, reaching 0 at the state border, where you happen to live.

The cows along the highway are evenly distributed, so if you count the cows as you drive, but restart your count every mile when you see the mile marker, you will reach the same number of cows every mile.

Now, the frequency is inversely related to the mile number. The frequency in this case refers to your children in the back seat asking, "Are we there yet?" They know damn well how far it is to home, because they can just look at the mile markers. Regardless, their rate of asking increases as the mile markers go down. When you're at mile marker 100, they ask once every 10 minutes. When you're at mile marker 1, they ask 10 times per minute.

If you instead look at the number of cows between "Are we there yet?" asks, then you will find that the cows-per-ask is much different from the cows-per-mile. At high distances (low frequencies), the cows-per-ask is very high, while at low distances (high frequencies), the cows-per-ask is very low.

Now, the article is looking at power-per-unit-frequency, so you'd actually have to measure the rate in change of how often the kids ask "Are we there yet?" And that would give you a little different result. You might need calculus to correctly calculate the derivative of the number of asks. But hopefully this illustrates that you can get different results, by using a different per-thing to measure your value.

There are 2 reasons:

  1. Those two graphs have different scales on the y-axis. One is Irradiance per nanometer of wavelength, and one is Irradiance per terahertz of frequency. Both graph's y-axis are called "spectral irradiance", despite being different things. This causes most of the distortion between the two graphs, and can even change the location of the absolute maximum.

  2. The graphs' x-axis have different units. This causes some distortion too, but wouldn't change the absolute maximum. It would help if they used a log scale in both cases, because wavelength and frequency are inversely related, so then the graphs could just be horizontally flipped.

So, look at the top graph (by wavelength), and see how much power is in that 1000-2000nm area. It's still a lot, just spread out over a large area. It's the same amount of power in the lower graph (by frequency) shoved into the much smaller area from 150THz to 300THz. Since it's in a smaller area on the lower graph, it has more power-per-unit-of-x-axis.

The Catholics are going to be in a difficult place as gayness becomes more normal. It's quickly becoming self-evident that homosexual relationships are not immoral at all. That's probably going to accelerate over the next few decades.

So the church should probably do more than just this to accept gay people, but they can't. Catholic rulings set by ecumenical councils or by the pope (in such a way as to invoke papal infallibility) can't be changed. It's like if the US constitution could only be amended if the amendments didn't contradict or repeal any existing text.

So if the church says "no homo, and that's final," then they can't go back and change it to "just a little homo, as a treat." It's hard to find an exact citation, but I'm pretty sure they've already said "no homo" enough to make it official, so there's no going back from that. Unless they also retract infallibility.

I showed him the thread, and he agreed. He was surprised by how strongly people felt about distros.

Personally, I think I never would have gotten as many comments as I did if not for mentioning the distro!

Yeah, Windows 7 is very old. It's definitely a concern. I keep him highly firewalled on the network so that hopefully he won't get hacked.

I usually play on Debian, but when I contacted Steam for support regarding Proton, they said they only supported Ubuntu or Steam OS. Since Steam OS isn't currently available for PC, that means Ubuntu.

C++ user with operator overloading: "T2 minus T1."

Let someone else implement the class. There's probably a library for it.

That site responds with a 403 forbidden error, which has a response body that says "VPN requests blocked."

I'm not on a VPN though. I'm on a residential ISP without anything unusual.

Could someone please send me that site's contact information, and/or figure out what kind of block list they're using?

Back when I worked at IBM, there were a bunch of flags hanging in the cafeteria that represented every country where IBM did business. We often wondered, why wasn't there a Nazi Germany flag? After all, IBM did sell a ton of machines to the Nazis to keep track of Jews and other undesirables, in order to commit genocide. I wonder why IBM wouldn't want people to know about that? /s

Anyone know where the Linux version is? Steam only has Windows and Mac OS versions. GOG only has a Windows version.

I'm assuming there is a Linux version, because this has been posted on https://old.lemmy.world/c/linux_gaming . If that is incorrect, I can't understand why it would be posted here.

Simon Tatham's Portable Puzzle Collection. Contains 40 puzzles of the Sudoku and Minesweeper sort.

It's free and open source, and available on a ton of platforms. On Android, I get it from the F-droid app store.

Well what am I going to farm and sell? If I can't make karma-whoring bots on lemmy.world, and then sell the accounts, what's the point? /s
