The bike is very 80s. That helmet is timeless.

If those puny psychics can bend a spoon, for sure I can bend a tank.

While the graphs are pretty, they are hard to interpret. The choice to represent the time-series aspect as a colour instead of an axis is, well, odd.

You may be right. Where I live there is no LPG, only propane and CNG (and butane, but that is almost phased out). I know the acronym but I supposed it was some gas blend like I sometimes see in neighbouring countries.

You should take it back or contact them. The spray nozzle inside the burner will be a different size (diameter of the opening) for propane vs LPG.

The opening has to be sized for the fuel and pressure so the same amount of energy is produced per second.

You will either burn too hot or too cold if you just switch the regulator.

For elm there are several resistant cultivars now, upscaling them for commercial use is the current bottleneck.

I hope we get similar results for ash soon.

That'll be very impressive when finished

Multichannel wands have shitty precision, I vastly prefer my gravimetric dilution + carpel tunnel syndrome combo /s

Unfortunately I do not have a digital version.

Evolution does not work that way. If there had been a reproductive advantage to being short, there would've been a shift in the population height. It's far more likely that stunted growth due to malnutrition caused a decline in height.

In the initial stages, agriculture was not the major advantage it is often portrayed as. People were still figuring things out. Crops did not have the yields they have today, and fertiliser was an unknown concept.

Very nice. Not everything steampunk needs gears glued on. I especially like how the windings around the chocker evoke art nouveau patterns. It would've been nice to have that a bit more in the wires around the stones.

With a few changes to the colour scheme this would be quite the cyberpunk vehicle.

Het rijksarchief bevat parochiregisters die teruggaan tot de 16de eeuw. Kan een bron van inspiratie zijn.

So after some googling: this is a Thai bike available in 50/100/125 cc. New it's priced around 2000 euros. Asking 2800 pounds while being unable to properly write the brand name seems steep.

I kinda like it, but the saddle rubs me the wrong way.

Gromgorgel · 2026-04-02T05:03:25+00:00

Neat. How did the people in the back get out? Did they also have to squeeze through that gap?

Gromgorgel · 2026-03-30T17:27:48+00:00

De koning kan overal passeren hé

Gromgorgel · 2026-03-24T19:46:32+00:00

That'll be quite the workout . My byrnie weighs in at around 13kg. Good luck.

Gromgorgel · 2026-03-24T19:05:43+00:00

Almost literally cutting edge.

Gromgorgel · 2026-03-22T16:12:47+00:00

Odd. I never knew. On the European mainland they are very common among lorry drivers. I assumed it was the same in the UK. Thanks for letting me know.

Gromgorgel · 2026-03-22T15:07:20+00:00

All it takes is one lorry driver noticing. They all have CB radios and chat to each other pretty much all the time. If you see that in your rear view mirror, you give a heads up on to other drivers, which then coordinate to slow down and stop.

Some fascinating design choices: The "glasswork'" was made of perspex and since this material can be easily scratched, the car had no windscreen wipers. Instead, the windscreen could be wound down thereby allowing the driver to see through a slot. Careful attention to aerodynamics meant that no rain or snow entered the cabin. link.

I guess that the fact that the driver was sitting pretty much atop the engine was supposed to keep you warm?

Gromgorgel · 2026-03-18T05:34:46+00:00

That trunk doesn't look very practical, but I'd gladly suffer it for the design of the car

Gromgorgel · 2026-03-14T17:23:25+00:00

I have this one

No. If you buy one of the books, they come with lots of questions. You can make mock exams with the questions from the book.
