Did you know that inside a common incandescent lamp there’s no vacuum but rather nitrogen and argon under slight pressure, and in the base of the lamp there is a fuse that interrupts the electricity flow to the filament as soon as it breaks?

So, this fuse also protects against the bulb exploding. If you’ve ever had bulbs explode, it means you ended up with fuseless bulbs, as these are sometimes found. The explosion is caused by an electrical arc which heats up the gas inside, making it expand and causing the bulb to burst loudly. An arc occurs when the filament breaks and under fortunate circumstances, it persists long enough to heat the gas. Initially, when the bulb is switched on, the current is higher due to transitional processes, which finally breaks the filament, followed by the arc and the burst.

It’s also interesting to note that the temperature of the filament inside the bulb is 3000 degrees. A gas absorbent is applied to the filament.

It’s very interesting to sequentially watch videos about light bulb production abroad and in Russia:

Today’s article about “Image Crop & Resize 2.0” – a product we created for a hybris contest at EPAM.

And in the end, we surpassed everyone and won! In May, I’m off to Orlando for a week for a hybris event. Work, work, it’s such a sneaky prize 🙂

Follow the link for screenshots, videos, and technical details.

Every time I go to fix small electronics, I feel like an inexperienced surgeon. Hands must not shake, half of it is held together by glue, the other half by clasps, always mindful of static electricity, one wrong move – death. And more and more electronics are poorly designed for repair. Sometimes it’s almost impossible to remove the cover without leaving traces.

“This Saturday, Masha and Liza participated in the ‘Kangaroo’ math Olympiad. Almost like home, but in America, at the ‘Metaphora’ language center. It was quite unexpected to find out that ‘Kangaroo’ is also held here.

The girls have been writing this Olympiad every year at their school in Moscow. It’s something familiar and dear to their hearts. First the problems, then the diplomas… And now ‘Kangaroo’ in America. For them, it’s like a piece of Borodinsky bread, gingerbread, or kissel. A sensation familiar since childhood.

They sat in the same classroom, at the same desk. One might think Masha could have quietly asked Liza everything a hundred times, but the Olympiad is a matter of honor 🙂

Honestly, it’s very pleasant. And after the Olympiad, there were pies. With apples, potatoes, cottage cheese. Almost like in a Russian school canteen :)” @[100001344249195:2048:Надежда Шульга]

I read on

about Safronov’s paintings and the opinion that they are printed on canvas. Indeed, there are printers that print on canvas. But then I found a robot that operates on a completely different principle – not line-by-line printing, but with real paints and a real brush. A very complex and interesting experiment
