Лекция: Тупики эволюции: почему вымирали люди? Станислав Дробышевский


Приятно думать о том, что сегодня человек — царь природы. Но оглядываясь на эволюционную историю человечества, ученые обнаруживают самые разнообразные вымершие группы (а иногда и целые виды) людей. Что служило причиной исчезновения больших популяций человека в прошлом? Большие природные катаклизмы? Или низкая рождаемость? Болезни и паразиты? О том, что уже заставляло исчезнуть целые виды людей, вы узнаете на лекции.

Лектор: Станислав Владимирович Дробышевский, к.б.н., доцент кафедры антропологии биол. ф-та МГУ

1891 German Weltrekord Ratchet Screwdriver - Restoration


It was around three months ago when I visited my friend that works at the steel waste. He made an amazing found. He found multible items that were in a very rough condition. They almost had some kind of concrete on them and a lot of heavy rust. This little screwdriver got my attention right away. It was not clearly visible what the function of it was, but I remember that I thought it might be some kind of ratchet mechanism. At home I posted a few pics of it in my Instagram story. It didnt took long for @hand tool rescue to reply, as he has the same screwdriver, just a slightly modern version of it, but similar mechanism. After some research I found some more pics and videos online. The brand is „Weltrekord“ made in Germany and its called „Hebelschraubenzieher“ which meas „lever scredriver“. The model I found was the first ever designed one from 1891. Weltrekord later made some small changes on the design. Newer ones have a small collet to clamp the insert bits and even newer ones came with plastic handles instead of wood.
At first I thought this will be a quick straight forward restoration project. It turned out to be a very tricky one. The most difficult part was definitely the disassembly, it took me three full days to get it in pieces. Heavy rust has done so much damage to all of the parts. Unfortunately the handle cracked when I removed it. I tried to restore it, but it became a huge mess and I decided to make a new one to have a nice and clean look. Theres a 40 minutes version of this video on my Patreon page where I show how I tried to repair the handle. I had to weld up material on a lot of parts and machined and sanded it clean afterwards. That all worked perfectly fine. Some parts have still very slight pitting but overall it turned out very well. For the finish on the steel parts I decided to try nickel plating for the first time and it worked fantastic. I went with a brushed finish and with the nickel coat the parts turned out amazing. I really like the look of the nickel plated parts with the wooden handle.

I hope you like my work and the video.

Тайм-менеджмент, дискриминация и чувство вины | Александр Сорокоумов | TEDxNiamiha


This talk was given at a local TEDx event, produced independently of the TED Conferences. Что, если все книги по тайм-менеджменту были написаны лишь для рациональной половины человечества? Что делать, если вы принадлежите ко второй половине? Если все ваши усилия по планированию приводят к нулевым результатам? Как избавится от чувства вины при виде бесконечного списка отложенных дел? И можно ли выжить во всем этом хаосе?

Change is life | Dr. B M HEGDE | TEDxGlobalAcademy


NOTE FROM TED: Please do not look to this talk for medical advice. We’ve flagged this talk, which was filmed at a TEDx event, because it contains sweeping generalizations and medical fallacies. The assertions about medicine are based on the speakers own theory and lack legitimate scientific support. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf

The contemporary medical research has come up with enough evidence that mind is the seat of all diseases and that we are surrounded by myths. Dr.B M Hegde is a medical scientist, cardiologist, educationist and author who has contributed immensely in the field of healthcare medical science. He speaks about how change is found everywhere and that change is life. He talks about the level of difficulty seen in removing myths. He cites the examples of taking medicines for minor illnesses which otherwise could be cured by sipping hot water which destroys the virus or by using the readily available Indian herbs. A good doctor according to him is the one who empathizes and builds faith in his patient. He says that change is a must and science has to change. He stresses on the fact that knowledge advances by changing myths and not by repeating the known things. This talk was given at an independently organised TEDx event using the TED conference format. Dr.B M Hegde is an Indian medical scientist, educationist and an author. Dr. Hegde is Padma Bhushan awardee 2010. He is the former Vice Chancellor of Manipal University, Co-Chairman of the TAG-VHS Diabetes Research Centre, Chennai and the chairman of Bharatiya Vidya Bhavan, Mangalore.
