Can you give an example of the kind of physical (mechanical?) representation you have in mind? How would you reconfigure it to play what-ifs with more than one equation or model? Graphing calculators and their online equivalents (e.g., desmos.com) offer a much more practical and flexible way to...

Doubt I could follow a riding script for even 20 mi. Operationally, you segment the planned route in some way. Then you assign an anticipated rider power and assist level to each segment, as if they'd be effectively constant throughout. This gives the rider an effort+assist script to follow...

Governent support for education is an important side of this, to be sure. But I was talking about student interest and STEM literacy in the general population. Not talking about higher math or rocket science here. A widespread grasp of beginner algebra would help. Algebra isn't just about...

Also tough to have a democracy when critical thinking's become a lost art in the general population. And it's well on the way to lost here in the US. If nothing else, STEM education teaches critical thinking and the importance of evidence. Autocrats and religious zealots do everything they can...

Amazing agreement over such a long hilly ride! How well did your wife stick to the riding script you put into the app to get the 11.3% prediction? We'd love to see your TQ bikes and the places you ride them. My 3 favorite forum threads are the ones for sharing ride photos...

One of the best jokes I've heard in a long, long time! Not that I can relate, of course. If I could give it more than 1 laughie, I'd give it 10.

Believe me, STEM educators are trying hard to find new and better ways to teach their subjects. But in a youth culture that generally values none of this and thinks it's totally uncool, it's akin to educating rocks. In other words, the problem's at least as much a cultural resistance as it is a...

The HOA is repainting all the houses in the neighborhood. They just did the neighbor's house while he's away. Supposed to be keeping an eye on things for him, so I texted an update: In a 'what the heck' moment, I just opened the first photo in my phone's image editor and told the AI tool...

Sorry, really thought those standard symbols (€ for Euros, L for liters, $ for dollars, gal for gallons, €/L for Euros per liter, etc.) would speak for themselves — at least to folks who remember a little algebra. My mistake. Using symbols instead of words to work out general patterns is a...

Sorry, this strikes a nerve. In the last few decades, popular culture's come around to the view that STEM subjects (science, technology, engineering, and math) are boring and useless — certainly not something a cool kid would show any interest in. It's OK to blow them off. Who needs them...

Riders carrying personal effects Guessing World Tour riders are all big weight weenies. And if they aren't, their teams surely are. So what's with the 3 gold-looking necklaces a spent Demi Vollering had on when she crossed the finish line today to win Stage 8? This was a hilly stage where...

Let the units guide you through the conversion. For this purpose, you can multiply, divide, and regroup the unit symbols as if they were numbers. $/gal = (€ × $/€) / (L × gal/L) = €/L × ($/€) / (gal/L) = €/L × K, where K = ($/€) / (gal/L) = $/€ × L/gal is your single conversion factor in...

Ebike safety video made by my pro-ebike state assemblymember Tasha Boerner: She's written several bills that support legal ebiking and try to deal rationally with the safety issues at the same time. Some have passed. When it comes to ebike regulation, California and New Jersey are very...

Let's see, average climb rate = 3300 / 26 = 127 ft/mi. You have every right to be completely knackered. Think I see Dan in black, standing in the grass roughly between the tree at the right edge of the photo and the nearest cliff. Appears to be waving to the camera. Could be on or near a...

Interesting indeed. Stunning solo win of TdFF Stage 7 from 9+ km out by former TdFF winner Kasia Niewiadoma Phinney, putting over 2 minutes into Vollering and Reusser in the process! All in the thick of the brutal Mount Ventoux climb!! This put KWP into the yellow jersey with fellow former TdFF...

That's certainly in line with what I'm seeing in this TdFF, especially Stages 5 and 6. With Mount Ventoux just 6 km ahead now, today's Stage 7 should be pretty interesting, too.

Windy app says 76°F water today. Thanks to an ongoing marine heatwave off SoCal, this is some 3-4°F above seasonal averages. This marine heatwave is about sea surface temperatures, not air temperatures. It will be compounded by the El Nino event expected to arrive later this year.

Having grown up in central North Carolina — where 95° and 95% is a pretty typical summer day — I don't allow myself to use the word "hot" in connection with the weather here, right on the San Diego County coast. But today's unusually high temperatures and humidity were definitely approaching...

I've been struck by how often we see this scenario: The breakaway stays away for 10s of kilometers, only to get caught in the last few km — sometimes the very last km. IMO, way too often to happen by chance alone. So you guys are saying that it's the peloton's or chasers' intent?? In a sport...

Wait, THEY'RE the Borg?? Well, if that's what the Borg's really like, I think it's high time to give them their own Star Trek spin-off.
