The Horn of Helm Hammerhand

Welp. May I add that there are now so many allegations, now from fully reputable sources, that it's time for things to be worked out in court. It's also worth noting that if you have that person's books from Audible, Audible is fully refunding your purchase.

It's also come out that this person has been long-banned from teaching in certain workshops for creeping on the students. Which, you know, is the power dynamic writ large. It's also a reminder that what any area of any industry considers an open secret really isn't open at all, and that whisper networks are heavy on the whisper, very light on the network. They really only protect people who are already have some level of protection due to industry ins.

It's a lot. And NO I'm not mentioning the name because the last thing I want in my life is pile-ons from folks who haven't really processed what all this means for themselves yet.

Taking out ads here is relying on this site's odd culture around him. "Favorite Tumblr Cryptid" and the like.

It's exploiting all the awful parts of fandoms. (Those parts are why I don't participate in them.)

Anyway. If you see that shit, don't click. I don't know if you can report it as inappropriate or whatever, but if you can, do.

I've been watching the track events at the Olympics since I was a wee lad. It was a tradition in our family. We'd gather around our ancient low-definition 19 inch CRT television and watch tiny blobs compete against other tiny blobs and root for our country.

It was a bit like watching YouTube on your phone in 144p.

Several heroes emerged.

Jackie Joyner-Kersee was amazing.

You can't forget about Flo-Jo.

And then the Olympics decided NBA players were allowed in the competition.

Which formed... The Dream Team.

Was this fair?

Well... they won each game by an average of 44 points.

So... no. It was not fair.

Though it became more fair as time went on.

But, umm... yeah. The other teams looked like the Washington Generals and the US looked like the Harlem Globetrotters if they stopped screwing around half of the game.

But my absolute favorite Olympian was a runner named Michael Johnson.

He was cool as heck.

For one thing... gold shoes.

But he also had this crazy, upright, Tom Cruise-ish sprinting style that just made him look like a running robot on the track.

And in the 1996 Atlanta games he just trounced EVERYONE. I mean, it wasn't even close.

Yikes. Those losing blobs are probably really embarrassed.

Last night I decided to invigorate my nostalgia and watch the track events again. And I got to see one of the wildest races in history.

It didn't even last 10 seconds but it was one of the most exciting sporting events I've ever witnessed. Almost every runner won the race.

After I saw that initially, I was like... who the heck won???

Even in slow motion I wasn't sure.

This was one of the closest finishes in history. There has never been a race where all 8 runners were within this margin.

The arena was silent as the winner was being confirmed. The runners just kind of paced around waiting for official word. My best guess was the Jamaican runner, Kishane Thompson. But then the loudspeaker announced Noah Lyles.

The last tiny morsel of American pride burst out of me with a big "Wooooo!"

I forgot what it was like to be proud of my country. I wish it happened more often. But this young man, despite being last place in the first 3rd of the race, turned on the afterburners and won in a photo finish.

And that's when my inner nerd took over.

Because when they showed the photo finish image, it looked super weird.

Why is the track white?

Why do all of the runners look all warpy like that QWOP game?

So I went down a research rabbit hole to figure this out.

Photo finishes are actually fascinating. The first photo finish captured the end of a horse race in 1890. But that was mostly luck and timing. The actual photo finish mechanisms weren't used until 1937.

Originally they would film the finish line through a physical slit.

And the first horsie head that appeared in that slit would be the winner. This technology ended a huge aspect of corruption in horse race fixing almost overnight.

But we have come a long way since then. And I'd like to introduce you to the Omega Scan 'O' Vision Ultimate.

This slow motion camera sits fixed on the finish line of every race. The concept of the photo finish has remained remarkably similar to the 1930s approach. The camera sensor is specially designed to only record a vertical slit.

Only the finish line itself is actually captured.

And because it limits what it records to only that slit, it can capture 20,000 frames per second to get amazing temporal resolution.

So why don't the photo finishes just look like, well... this?

That is because the camera takes a picture of time more-so than dimensional space. I guess it would be more accurate to say it *assembles* a picture of time.

As the runners cross the finish line, the camera combines all of the little strips of pictures into a single image.

It's almost like if you tried to reassemble a piece of paper after it had been shredded.

Imagine each strip of paper is a picture of ONLY the finish line, just at a slightly different point in time.

What if someone stopped on the finish line and didn't move... what would that look like?

Once they got there, the same part of their body would just be repeated.

So the right side of the photo finish picture represents earlier in time and it just assembles the image strip by strip as time passes and you literally get a picture of time itself.

NEAT!

Okay, but how do they determine the winner from the photo finish?

I mean, that shoe looks like it is ahead of Noah Lyles!

Clavicles!

The IAFF rules state the foremost part of the torso must cross the finish line first. And the endpoint of the torso is the outer end of the clavicle.

So if you get this bone across the finish line first, you win the race.

Two more fun facts!

The start of the race is actually just as carefully timed as the end of the race. There are sensors in the starting blocks of each runner.

The starting gun also has an electronic sensor.

They have determined the fastest a human can react to the sound of a gun is roughly 100 milliseconds. So if you start running before 100 milliseconds they know you didn't actually hear the gun, you just got antsy and started running too early.

And the final fun fact...

Did you notice the Omega logo at the top of the photo finish?

That isn't superimposed or added after the fact. That is captured by the camera.

But if this image is composed only of tiny little slivers, how did they get the Omega logo to show up?

That is a little display. And it is synchronized with the Scan 'O' Vision Ultimate to show a little sliver of the Omega logo for each frame captured.

So when the final image is stitched together, it looks like a cohesive logo at the top of the photo.

Then I watched a video that said it could do 10,000 frames per second.

Then the website said it could do 20,000.

I was all, "WHAT IS THE TRUTH, OMEGA?"

I finally realized the first video was from 11 years ago. The second was from 3 years ago. And the website is current day.

Technology!

I also tried figuring out how much a Scan 'O' Vision costs, but there is not a single price listing on the internet. All of the websites say "inquire for price" which usually means it costs more than a house. That tracks since the Phantom Flex 4K slow motion camera costs about $110,000. Plus you are probably paying for the system and the software and the setup as well.

It's expensive to know who won a race.

Also, I didn't include Usain Bolt among my favorite Olympic athletes because when I first became an adult I stopped paying attention to the Olympics and missed that era of sprinting. But I've since watched videos of him running and I truly wonder if anyone will be that fast again.

Yesterday, Noah Lyles ran the 100m in 9.79 seconds.

Usain's word record is 9.58.
