Evrimsel süreçte kimi zaman bildiğimiz hiçbir canlı grubuna uymayan, öylesine tuhaf ve büyüleyici organizmalarla karşılaşırız ki paleontologların bu canlıları sınıflandırmakta neden bu kadar zorlandığını çok iyi anlarız. İşte Tully canavarı (Lat: "Tullimonstrum gregarium") tam olarak böylesi bir canlıdır.…

People I’d never heard of

I think I mostly hang out with the right people (although, I was associating with a bad crowd when I was active in that New Atheist thing), because the news keeps popping up with all these horrible people I knew nothing about until they committed their crimes. Which is not surprising, since that’s how news […]

I’m pretty sure we have no flat earthers here

But if we do, let’s smoke them out. For those unfamiliar with the region, Mt Rainier (correct spelling) is about 80 miles (130 km) north-north-east of Mt St Helens. That photo is a good visual aid for refuting flerfs. Argue away! Or can I expect dead silence because no one is stupid enough to fall […]

A long long night at the motion picture show

We’re strapped for volunteers at the Morris Theater because it’s Hallowe’en and there are so many events going on, so last night I did a triple-shift, sort of. The first show was The Other Mommy, which has received such dire reviews that I didn’t bother to watch it — and neither did anyone else, apparently. […]

We had our first trick-or-treaters of the evening

Three little kids, the youngest no more than 3 years old…and our evil cat tried to kill them. Seriously: hissing, spitting, snarling, clawing at them, and I just managed to intercept the attack with my foot. After they escaped, she was prowling by the door, evil in her eye, waiting for her next victim. She […]

The latest corruption scandal in Minnesota

There’s a sleepy little town, Appleton, just a few miles south of Morris. I’ve visited it a few times to check out the spiders there — there’s no other reason to go there, it’s not much of a tourist attraction. Population 1400, no particular businesses there, they had a defunct prison that was shut down […]

No “blue wave” — can we get a wave of thoughtful voters instead?

I must express my gratitude to Hayley Stevens. She lost a primary election for the Michigan senate to Abdul El-Sayed, but promised to endorse him anyway, and then over the weekend, just before the midterm elections, changed her mind and endorsed the Republican candidate, Mike Rogers. It was a breathtaking betrayal. A stunning stab in […]
