It’s rough out there. One day you’re the plague. The next day you’re the victim of the plague. Some real “Live by the sword, die by the sword” stuff going on in the animal kingdom.

Brave New World and Fahrenheit 451 are such incredible books to read today because every time you set the book down to check your phone, you feel like the worlds biggest asshole.

@HippyMomPhD Heard someone say that everyone has a “magic number”, which is the number of times they need to practice something before it “clicks”. Some people have a magic number <10 and some people have a magic number > 100. Sometimes we call people “individuals” for a reason.

I'm starting to wonder if teaching conceptual math heavily is making it harder for a lot of kids - hear me out. They looked at students who were gifted in math & went "huh, they think conceptually. We should teach everyone conceptually" My youngest is gifted in math. She just "gets it" It's absolutely conceptual to her - and easy. But my oldest, nope. And no amount of me explaining the concept ever helped her. You know what did? Procedural practice ... over & over & over. Then, something kinda like magic happened. She looked at me this week and said "oh, I get it!" and she then explained to me the concept I'd tried to teach her a year ago. Don't get me wrong. Conceptual math for prek-2nd grade is great. But I'm not convinced it's the best path long-term. Conceptual learners - already "get it." The strugglers.... might just need a LOT more practice before that light bulb goes off. Thoughts?

@HippyMomPhD Had a similar experience with an art history class from an art prof (I was a math major). Teachers who deeply love their subject and are good storytellers are worth their weight in gold.

In college, I had to take an anthropology class (outside my major - I didn't want to) The prof LOVED his subject. He told stories of ancient peoples & his experiences running about central america. The class was riveting & I never missed a class. I didn't change my major, but TO THIS DAY I remember it & what he taught me. His class are more vivid in my mind than most of the profs in my own major. There is a lesson here. You have to LOVE what you do. Tell it like a story. Make it impossible to ignore -- and you influence lives decades later.

You need to understand that Silicon Valley is increasingly being run by creepy, dead-eyed men who hate families, who hate kids, who have no respect for life, who would like to see much of humanity dead or enslaved. It’s our job to defeat the dystopia they’re so eager to build.

Truly one of the great monuments to human ingenuity!

The signal strength hitting Earth from Voyager 1 is less than one trillionth of a watt. To put that in perspective, your phone’s WiFi signal is roughly 100 billion times stronger, and it drops a connection walking between rooms. NASA picks up Voyager’s whisper using arrays of 70-meter antennas, then reconstructs coherent data from it at 160 bits per second. That’s slower than a 1990s modem. Downloading a single photograph at that rate would take weeks. The spacecraft itself runs on 8.8 kg of decaying plutonium-238 that generated 470 watts at launch in 1977. Today it produces roughly 200 watts, losing about 4 watts per year. NASA has been shutting down instruments one by one since the 1980s to keep the math working. They turned off the cosmic ray sensor just this year. And here’s the part nobody’s talking about: there is exactly one antenna on Earth that can send commands to Voyager. Deep Space Station 43 in Canberra. It went offline for major upgrades from May 2025 through early 2026. During that window, if Voyager had a critical fault, the team would have had to wait months to respond. A 48-year-old spacecraft built on 1970s computing, running on a plutonium battery that’s lost 60% of its output, transmitting at a power level that barely qualifies as existing, from a distance where light itself takes 23 hours to arrive. And a German observatory just casually picked up its carrier signal on a live stream. The engineering margin NASA built into this mission was designed for 4 years to Saturn. Everything after that is borrowed time the engineers keep extending by doing math with 200 watts.

Happy "Solar Spring"! Today is the mid-point between the the Winter Solstice and the Spring Equinox, marking the quarter of the year of most rapid daylight gain. We're now gaining over 2 minutes of daylight every day and this will continue until May.

Students like this should be forced to set piles of cash on fire in the quad and made to watch it burn.

Imagine paying thousands of dollars to take a class just to go to class and play games to *checks notes* distract yourself from the content…
