Cool Christmas tree

An interesting feature – in recent years, in fact, only my family (two numbers) and strangers who want to sell me something call my phone. And this happens to many others, so they don’t answer these calls from unfamiliar numbers at all. And I have stopped too. It seems that in my world, the mobile phone is gradually assuming the role that the landline telephone had years ago. Messengers and texts are everything for us. Contacts with the outside world – only on my own initiative. But almost always these outgoing calls go to a call center. It seems that in such a system, corporations should restructure the way they communicate with clients. They need to provide the possibility of a callback at the request of the caller, with one click. Something like an app – let it be one for all call centers participating in the program. There, you fill out a form, press the “Call me” button, and wait for a call within the next half hour. And the operator already knows what you are calling about, and speaks directly to the point of the matter.

An excellent lecture in an “Explain-Like-I’m-Five” format by Anna Urum about CRISPR/CAS and genome editing. Anna is a student at the Department of Genetics at the Faculty of Biology of Moscow State University, and a staff member of the Cell Biology Laboratory at the Russian Federal Research Clinical Center of Federal Medical-Biological Agency, and despite her limited experience, she is very commendable

Day twenty-four, night – minus one;)

From the online store: “Your robot vacuum is leaving us negative reviews and asking to be picked up”

The uncle is very cool. Awesome ragtime performance

Today I am presenting in Kyiv (remotely).

I was there exactly six years ago, on March 25, 2013. It snowed. There was an emergency. I didn’t get to see the city because there was no means of transportation – everything was out of order 🙂 APCs helped trolleys not to slide down the hill backwards and block the passage for the few SUVs. The ‘U’ in a triangle on the APC was amusing in itself)

It turns out that the reason why most Unified State Exams (USE) last not 4 hours, but 3:55, is because, according to SanPiN 2.4.5.2409-08, if a child is in school for more than 4 hours, the school is obliged to provide a hot meal.

An intriguing little life hack for calculating percentages:

X% of Y = Y% of X

So, for example, if you need to calculate 4% of 75 mentally, just swap the numbers and calculate 75% of 4, which is much easier.

Understandably, this is somewhat obvious from a mathematical point of view (100 in the denominator moves to the second factor), but nobody has been doing this in mental calculations, right?
