Brilliant.org Reviews

Math Made Easy: Best Apps Like PhotoMath
Brilliant is like the philosopher of math solver apps. It’s not just about getting the answer; it’s about understanding the why and how. It’s like a deep dive into the world of math and science.

Cal.com Reviews

I've poked around a while ago at some Calendly alternatives (specifically was lo... | Hacker News
I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • Ask HN: What is a good website/app for math practice?
    I have always enjoyed using https://brilliant.org/ because it's interactive and very informative. Although it's not as interactive, https://artofproblemsolving.com/community offers a great community and valuable resources. - Source: Hacker News / 13 days ago
  • Ask HN: Good sources of math exercises for ~10-17 y/o?
    I used Brilliant (https://brilliant.org/) with my kids and it was helpful, if only because they did try to explain some of the theory around the work in different ways. Considering your comment around videos and artwork, it might not be what you are after, but you can check out some of their free courses to get an idea of how they work. The biggest issue for me was that it is concept based rather than curriculum... - Source: Hacker News / about 2 months ago
  • on discouragement
    So, I started studying from the basics with brilliant.org about 4-5 months ago, starting right from the basics. I do it for 40-45 minutes every day, no exceptions, making it a priority just like reading books. From what I've observed so far, I enjoy it. Sometimes I do well, encountering old topics I've learned before. I dare say one of my hobbies is math study (i'm not sure how far I can go, but I ask myself how... Source: 7 months ago
  • combining like bases with exponents when there's a fraction involved
    Can someone write this out in a super-explicit form to show me the rule for how to combine like bases - this is another brilliant.org question:. Source: 8 months ago
  • Looking for a website to learn fundamentals
    I'm a chemical lab assistant and have worked in biochemistry/protein research for four years. I do good work, but I want to understand more background. Often, I don't get the theory behind my experiments. So, I want to build my fundamental knowledge and more. I liked brilliant.org. But there is no biochemistry. Do you know a similar website that would help me? I will also welcome more help. :). Source: 9 months ago

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: 7 months ago

    Has any one deployed cal.com with selfhosted environment. Is yes how would have configured prisma for the same. Source: 9 months ago
  • Open Source, EVERYTHING??
    Recently I came across a company called cal.com, it's a Calendly alternative, but the catch is the entire software is open source: https://github.com/calcom/cal.com. Source: 9 months ago
