The August 2nd, 02027 eclipse will sweep from Gibraltar across North Africa, passing over Luxor, and onward to Arabia. Near Luxor, Egypt, totality will last for ~6 minutes 23 seconds. This will be the longest total eclipse over land until 2114. The Pyramids of Giza are not in the path of totality.

My family went on a cruise last Christmas and we somehow found ourselves discussing how many miles it takes for a cruise boat to come to a stop. The physics on this isn't too bad, so I worked it out over dinner.

The morning of the 2026 solar eclipse I stood in a room full of friends and strangers while someone tried to wrangle cars. "Who here has seen a solar eclipse?" he asked. A bunch of hands went up. "And who thinks it was the coolest thing they've ever witnessed in their entire life?" The hands stayed up. "I would recommend for your life that you go --- you won't know any different --- but the other path is better."

I sent one of my Prius fobs through the laundry a few years back and, ever after, the electronics just didn't work.

In my previous post I worked out how a negative carrier test for an autosomal recessive disorder updates a sibling's risk. Not much, as it turns out, unless the background rate is already quite high. ApoE is more interesting because it involves three common alleles.

My niece was looking at buying a new WiFi router, but wasn't sure which was best. The following were my suggestions.

I recently had a genetic panel done. Hundreds of genes were tested and I came back as a carrier for a couple of things. This isn't surprising:
