Дилемма заключённого — известная задача в теории игр. Самая выигрышная стратегия в ней — предательство. Но что если эту дилемму нужно решать многократно? Скажем, каждый день вам нужно оставлять свой контейнер с едой в офисном холодильнике. Стоит ли покушаться на чужой йогурт? Или дождаться, пока кто-то оставит вас без колбасы, и уже тогда принимать меры? Проблема нешуточная. А как её решать, рассказывает Дерек Маллер в новом видео Veritasium.

I have been obsessed with measurement for a long time and I'm not sure quite how it happened. The world's roundest object played a role in this. I guess I'm just fascinated by how difficult it is to pin down a quantity like a kilogram. A physical object seemed like a good idea until the mass of the international prototype kilogram wasn't as constant as expected. These methods of the Kibble balance and silicon sphere have shown better precision than 20 parts per billion, making them superior to the old method. The agreement between Avogadro approaches

الإيروجل مادة لديها ميزات خلابة ولكنه صعب التعامل بها. نبحث بهذا الفيديو عن تطور مادة الإيروجل واستخدام ميزاتها العديدة. اشتركوا في قناة فريتاسيوم بالعربي

شكر خاص للدكتور ستيفن ستاينر وطاقم العمل في ايروجيل للتكنولوجيا. للمزيد من المعلومات أو لشراء مادة الإيروجل:

شكر للدكتور ستيفن جونز والدكتور ميهايل بيتكوف من مختبر ناسا للدفع النفاث.
وشكرا لـ "فلير" لإعارتنا هذه الكاميرا الحرارية عالية الدقة. كانت نتيجة التصوير مذهلة!
https://www.flir.com
ميزات مادة الإيروجل الاستثنائية هي بشكل كبير نتيجة لهيكلية المادة. بالرغم من أن مادة الإيروجل تعتبر صلبة هي اسفنجية على مستوى لمقياس النانو، والمسامات الهيكلية الاسفنجية على صغر 20 نانو متر تقريبا. هذا الذي يجعل سيليكا الإيروجل خفيف جدا وشفاف ومادة ماصة أيضا (اعتبرت سابقا أخف صلب في العالم لكن حل محلها الآن مادة الجرافين ايروجيل).
حبة إيروجل بحجم مكعب ثلج لديها مساحة سطحية داخلية تقارب نصف ملعب كرة قدم. تستخدم مادة الأيروجيل في المتاحف لتنظيم مستوى الرطوبة. إضافةً تساعد في الحفاظ على الهواء داخل مقياس الزلازل المستخدم على كوكب المريخ - تمتص الرطوبة والغازات المتصاعدة الأخرى التي تخرج من المكوك الفضائي. مقترحات اخرى لاستخدامها تتضمن استعمالها كمبيد جسدي للحشرات لتجفيف الحشرة كبديل للمبيدات الكيميائية والسامة.

An atom is mostly empty space, but empty space is mostly not empty. The reason it looks empty is because electrons and photons don't interact with the stuff that is there, quark and gluon field fluctuations.
It actually takes energy to clear out space and make a true 'empty' vacuum. This seems incredibly counter-intuitive but we can make an analogy to a permanent magnet. When at low energies, like at room temperature, there is a magnetic field around the magnet due to the alignment of all the magnetic moments of the atoms. But if you add some energy to it by heating it, the particles gain thermal energy, which above the Curie temperature makes their magnetic moments randomly oriented and hence destroying the magnetic field. So in this case energy is needed to clear out the field, just as in the quantum vacuum.

People claim that 70-80% of household dust is dead skin, but is it true?
Thanks to Google for sponsoring this video! Learn more about Search here: https://www.google.com/search/howsearchworks/
Special thanks to J.M.E.H van Bronswijk, author of 'House Dust Biology'. We exchanged emails to make sure I got my facts straight for this video. Below is an excerpt from her email to me, responding to my claims that start with a dash:
- Around half of airborne dust particles under 100um are skin scales
This is true for climates, regions and seasons where people live mostly indoors.
The 1 to 2 g of skin scales shed each 24 hours will end up in places where people are present (and rub their skin or have textile moving over the skin).
You can also look at it from a different angle: What else has the same size and could contribute? That will usually be pollen from outdoor sources, also depending on season, region and climate, as well as the ventilation regime of the building.
However, taken as the median value over a whole year, I consider your statement correct for regions with a temperate climate.
- 53% of dust particles vacuumed from a mattress were found to be skin scales
It depends a little on the type of mattress. For polyether mattresses the amount may even be larger.
For mattresses made of natural material it could be less since the mattress-material will also give off small particles.
- larger particles consist mostly of fibers, eg. cotton, paper, wool, synthetics
That's true .. including bread crumbs ..... 🙂
- skin scales seem to form a larger fraction of dust where we spend more time, e.g. in or near bed.
..... and on the couch used to view television or be active in gaming.
It has to do with the constant production of skin scales over the 24 hours.
- skin scales form a smaller fraction of dust if there are significant other sources, e.g. carpeting, dirt from outside etc.
Yes, everyting you walk on with your shoes or that recieves dirt from the outside with other means, will have a lessr percentage of human skin scales.
However, do not forget the skin scales of pets that will also be an active allergen for many people, and a food source for house dust mites.
