Stuff that interests Mr Reid, a physicist and teacher. Physics of the Data Projector. I loved the Moviebarcode. Site that I found via MetaFilter. And wanted to create some barcodes of my own. After a bit of fiddling I managed to produce some reasonable facsimiles using a combination of VLC. This example barcode is from. Step 1 – Extract images. Vlc movie.avi - video-filter=scene - scene-prefix=movie - scene-ratio=90 - scene-path=c: movie. The important option is. Step 2 – Resize images. To create the bar...

Stuff that interests Mr Reid, a physicist and teacher. Physics of the Data Projector. Ben Hammersley tweeted that it would be cool to hear GLaDOS from Portal do the shipping forecast. I didn’t do the entire report because it gets a bit boring after a while, but as a proof-of-concept it seems to work. 2 thoughts on “ GLaDOS Shipping Forecast. 9th July at 14:39. This would be so cool with the BBC shipping forecast and it’s slightly psychedelic format. 3rd December at 11:08. Leave a Reply Cancel reply.

Stuff that interests Mr Reid, a physicist and teacher. Physics of the Data Projector. A problem by Paul J. Nahin. Each of a million people puts his or her hat into a very large box. Each hat has its owner’s name on it. The box is given a good shaking, and then each person, one after another, randomly draws a hat out of the box. What is the probability that at least one person gets their own hat back? We can view this problem as having only two possible solutions (events): either. Gets their hat back, or.

Perpetual motion machines of the first kind. Violate the First Law of Thermodynamics. They produce mechanical work (i.e. movement) without any energy being input; this violates the principle of the conservation of energy. Perpetual motion machines of the second kind.

Lines of longitude are great circles, each one the same size, running around the Earth and crossing both the north and south poles. When quoting the position of an object on Earth’s surface in terms of its longitude, the degree of precision is not affected by the longitude in question. 10 / 1.0 0′ 0″. Thinsp;11.1 km. 0 1′ 0″.
