An impossible star? No, it just means that we don’t know everything yet.

So stars are born, they live, and they die. Large stars die in a supernova. And that’s it.

Except that it isn’t. Scientists have found a star that has had multiple supernovas. One in 1954, the other in 1993. This is impossible given our current understanding of how stars work. Which means that we need to change our understanding. Our current theories are wrong and need to be changed. This is the exciting part of science, when our understanding has to change to fit the facts.

Research may help block unwanted thoughts

Have you ever had a thought that just keeps on coming up even though you wish it would just stop? This is very common with people who have PTSD, depression, anxiety, and more.

Research done at the University of Cambridge has found that one particular neurotransmitter, GABA, may be the key to help avoid these thoughts in the future. Research using FMRI and magnetic resonance spectroscopy have found that the presence of GABA can inhibit the activity of connected memory neurons. It may be that increasing the amount of GABA could help reduce the amount of persistent unwanted thoughts.

Spreadsheet Workshop

Today was an InService professional development day. Other teachers know what I’m talking about. I gave a workshop on spreadsheets, specifically google sheets, but it all also applies to Excel.

I love spreadsheets. They are so powerful and make things much easier—if you know how to use them. I’ve seen many teachers doing things that would be easier and faster if they used a spreadsheet.

So I made a spreadsheet to explain things like cells, cell addresses, simple formulas like SUM, AVERAGE, COUNT, etc. The teachers taking the workshop really liked it and immediately saw how this would be useful for them. The last part was on conditional formatting and they really liked that.

Most of the teachers went from knowing almost nothing about spreadsheets to knowing how to have a spreadsheet do math and other useful things.

… it wasn’t willing

So my son and I go to St. Joseph, MO to see the eclipse. And the clouds roll in. And it rains a bit. We get to see some of the partial before totality, but only get to see 4 seconds of totality. This is the pic I took with my phone:

The best photo I’ve seen from St. Joseph was this one.

Hope you saw a better eclipse than we did. Even so, experiment_1 said that it was worth it.

Play Wikipedia!

Back in the mists of time, like the 1980s, there was a genre of computer games called Interactive Fiction. This is where there is a story, and you’re part of it. You might remember those “choose your adventure” books where that say something like “if you want to go to France, go to page 17”. Well, Interactive Fiction is the computer version of those books. And the king of Interactive Fiction was Infocom. They made games like Zork, Deadline, Suspended, Moonmist, Trinity, and many more. There weren’t graphics, just text, and you filled in the graphics with your imagination.

West of House
You are standing in an open field west of a white house, with a boarded front door. There is a small mailbox here.

You can choose to go to the house, look around, read the letter in the mailbox, pick up objects, etc. Oh, you can play Zork here.

So what does this have to do with Wikipedia? Well, now you can play that in the same way. Choose a starting place, and see what’s there. Say “go north” (or just “n”) for short. Wander around the Colosseum, and more.

Go exploring!
