Helmhurts A few posts back I was concerned with optimising the WiFi reception in my flat, and I chose a simple method for calculating the distribution of electromagnetic intensity. I casually mentioned that I really should be doing things more rigorously by solving the Helmholtz equation, but then didn’t. Well, spurred on by a shocking [...]
Physics demonstrations: Faraday disk By turning a hand crank, one rotates a copper disk between a pair of magnets (the black disks), one generates an electrical current that runs from the outer edge of the disk to the central axis. Wires connected to these two points runs to the red and black plugs, through which [...]
While I was out with my FLIR One I noticed some bees pollinating the flowers on a bush and snapped some pics and took the video. They’re a tad warm. Flying is hard work. One thing I’ve noticed with my camera is that the visible and IR cameras don’t quite line up (I haven’t read [...]
Finally got my FLIR One thermal-IR camera working (the issue was with the phone to which it’s attached), and it’s amazing. This is my kitchen sink, with a bowl full of room-temperature water in it, along with some utensils, and the water on hot, aimed so it hits the basin rather than going straight into [...]
Every Insanely Mystifying Paradox in Physics: A Complete List I can’t vouch for this list being complete, and there’s the caveat that many (most?) paradoxes have perfectly sound explanations — it seems that sometimes paradox merely translates to not intuitively obvious — but it’s easy to get lost in some of these.
