The 37 Best Websites To Learn Something New

Forget overpriced schools, long days in a crowded classroom, and pitifully poor results. These websites and apps cover myriads of science, art, and technology topics. They will teach you practically anything, from making hummus to building apps in node.js, most of them for free. There is absolutely no excuse for you not to master a new skill, expand your knowledge, or eventually boost your career. You can learn interactively at your own pace and in the comfort of your own home. It’s hard to imagine how much easier it can possibly be. Honestly, what are you waiting for? here is the link


A student’s lecture to professors

Can students teach their lecturers a thing or two? Austin Fitzhenry thinks so:

  • Don’t cater to students who suffer from “entitlement complex”
  • Challenge the student
  • Move on – and don’t repeat. I repeat: don’t repeat
  • Forget the textbook, and focus on concepts
  • Instead of teaching to the test, encourage creativity
  • Give meaningful assignments – and don’t let students lecture
  • Don’t require attention or attendance
