I'm building a library of presets for the new #Wavicle app. This one demonstrates the metal grill in the door of a microwave oven blocking microwaves from escaping (long) while allowing light waves through (short).

Fantastic #MauiDay in London today highlighting some of the great work being done using it to create innovative cross-platform apps. I was particularly impressed by the talk about #MotiMe. Great example of the way technology can be used to help with child physiotherapy.

To support my new #Wavicle app (physics education) designed using the fabulous #DotNetMAUI I'm creating a video to explain the whole wave/particle debate. Or some of it. Here's a little timeline I made to go in it.

Didn't Picasso do stuff like that sometimes?
This one is 1705992 pixels long. At 300 dpi that would be about 158 yards.

"Unexpected path. Draw a route that changes direction based on one very simple rule."
The simple rule: "Follow the letters in Winnie-the-Pooh".
With this being a somewhat different style and age to Shakespeare, will there be a noticeable difference? No.

As you can see, with this letter-wheel Macbeth drifts left and down like Hamlet did. Probably pretty much what you were expecting.

The Falstad Ripple tank is:
a) a classic
b) has a bunch of secret levels?
And by secret levels, I mean an absurdly long list of presets I've never fully explored. Like this biconvex lens. (A LENS in a ripple tank?!? Amazing!)
What's your favorite secret level? ⚛️ 🎢

In a #DotNetMAUI app, why use the OS's built in keyboard when you can make your own? Fun to design, easy to draw onto an ICanvas and, once that little bit of effort is out of the way, infinitely configurable and unique. Don't follow the crowd. #ReinventTheWheel!

...and it's easy to show that removing one source and adding a reflecting barrier also creates an interference pattern, this time between the source and its reflection. The cross-section view can be used to examine this.

In my #TeachPhysics app written using #DotNetMAUI, you can easily add 2 sources of circular ripples and show how spacing of interference fringes changes with the spacing of the sources. Wide sources = narrow fringe spacing. Close sources = wide fringe spacing...

Slight discrepancy between the #DotNetMAUI build on Android and iOS: When stroke size is set to 0, ICanvas.DrawPath() draws thin lines on Android but doesn't draw anything on iOS. On iOS you have to set stroke size to 1.0f or leave it as the default value. No biggie.

I take it back. Having installed #VisualStudio2022 v17.14.13, the SSH connection to my #MacMini now works, and #WordyBlob has now been successfully built on it and is running in an iPhone 16 emulator just fine. Well done #Microsoft. But I reserve the right to get grumpy again at the next problem.
