This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Thursday - what a day!
We started out our morning with another symposium. Today's main speakers were Dr. Zahi Hawass, Egyptologist, and Dr. Daniel Oppenheimer, Professor of Psychology.
Mr. Hawass' talk was absolutely astounding: everyone in the hall were holding their breath, as he spoke of his amazing discoveries in Egypt, in the Valley of the Kings.
Mr. Oppenheimer, instead, talked about the flaws of our perception and our memory, and gave a live demonstration of that by involving us in very simple yet tricky psychological experiments.
After that, it was time for us to head towards Caltech! We had a quick glimpse of the campus, and then we went to listen to the presentation of five college representatives. Caltech is so awesome!
Back to Oxy, we concluded our day with a few other great talks, and then a massive chess tournament, in which 15 people at a time were playing against Jennifer Shadade - a chess grandmaster!
What a great day.
Lesson of the day: If you want to choose your path in life, you can't pick something that you just like; love isn't enough either; you must be truly passionate about it! Also, never trust your perception and your memort 100%, as tricking them is very easy!
Implanting a false memory is really easy if you know how to do it. You can do that by continuously lying to someone as well. Sometimes using certain words could distort your approximation abilities and memories.
Do you see the the words 'a little less' on this note? Those words are not co-incidental. Although this does not affect people's memories, it does help me make them think what I want them to think a lot easier.

Well, the test is simply astounding as to how our memory can record a false observation! Thanks for sharing! Enjoy the remaining days at the AOTM.
One of the experiments was like this: he showed us a list of 20 words for a few seconds, and he asked us to memorize them. Then, he changed the slides and started talking, in the attempt to distract us. Next, he asked if we remembered the first and the last words, and everyone got them right. Then, he askes us if we remembered a word that wasn't in the list, and almost everyone fell for it!
He then explained how easy it can be, given the right conditions, to create a false memory.

Can you describe the live demonstration that memory is not to be trusted? I'm always intrigued by such events.

Try this out.
