Strings aren't useful

This decision is being seconded by an increasing number of physicists and highlighted by that writer.

String Theory can be used to explain an amazing array of physics features — but unfortunately, we’re left with String Theory itself being, in effect, non-resolvable. So we have “explanations” that don’t also bring us real answers.

The reporter asks:

If fewer physicists were tied to strings might some of the enduring mysteries of the universe be solved? Might we know why there is more matter than antimatter? Why the proton's mass is 1,836 times the electron's? Why the 18 key numbers in the standard model of fundamental particles have the values they do?

...and extracts the professional opinion...

"With smart people pursuing these questions, more might have been answered," says Mr. Woit. "Too few really good people have been working on anything other than string theory."

That string theory abandoned testable predictions may be its ultimate betrayal of science.

...or in other words, ST went for interesting progress rather than going for real answers, and science is (supposed to be) about finding real answers.

new life for an old (FTX) PSU, improved life for one human

the LEDs on this 5m strip happen to emit light centred on a red that does unexpectedly helpful things to (and surprisingly deeply within) a human routinely exposed to it. it has been soldered to a Molex connector, plugged into a TFX power supply from a (retired: the MoBo is cactus) Small Form Factor PC, the assorted PSU connectors (and loose end from the strip) have been taped over. the LED strip cost $10.24 including postage, the rest cost $0, the PSU is running at 12½% of capacity, consumes less power than a laptop plug-pack despite running a fan. trial runs begin today.

I have a LibreOffice Impress slideshow that I wish to turn into a narrated video. 1. export the slideshow as PNG images (if that is partially broken — as at now — at higher resolutions, Export Directly as PDF then use ‘pdftoppm’ (from the poppler-utils package) to do the same). 2. write a small C program (63 lines including comments) to display those images one at a time, writing a config file entry for Imagination (default transition: ‘cross fade’) based on when the image-viewer application (‘display,’ from the GraphicsMagick suite) is closed on each one; run that, read each image aloud, then close each image in turn. 3. run ‘Imagination’ over the config file to produce a silent MP4 video with the correct timings. 4. run ‘Audacity’ to record speech while using ‘SMPlayer’ to display the silent video, then export that recording as a WAV file. 4a. optionally, use ‘TiMIDIty’ to convert a non-copyright-encumbered MIDI tune to WAV, then import that and blend it with the speech (as a quiet b...

boundaries

pushing the actual boundaries of the physical (not extremes, the boundaries themselves) can often remove barriers not otherwise perceived. one can then often resolve an issue itself, rather than merely stonewalling at the physical consequences of the issue.
