Mıknatıslar Neden ÇALIŞIR? Feynman'ın Açıklamayı Reddettiği Tek Soru
Richard Feynman'ın 1983'teki efsanevi BBC röportajından ilham alan bu videoda; fiziğin neden "neden" sorusuna değil de "nasıl" sorusuna cevap verdiğini ve neden tanıdık açıklamalar beklemenin sizi her zaman tatminsiz bırakacağını inceliyoruz.
Manyetizma Zamanın geriye akmasıdır!

<p>Although most of us simultaneously accept the premise that magnets are quite literally everywhere and that few people know how they work, a major problem with magnets today is that they tend to rely on so-called rare-earth elements. Although firmly in the top 5 of misnomers, these abundant elements are hard to mine and isolate, which means that finding alternatives to their use is much desired. Fortunately the field of high entropy alloys (HEAs) offers hope here, with [Beeson] and colleagues <a href="https://advanced.onlinelibrary.wiley.com/doi/10.1002/adma.202516135" target="_blank">recently demonstrating</a> a rare-earth-free material that could be used for magnets.</p>
