Transcript

[APPLAUSE] MATT PARKER: Thank you. Thank you. Oh. Wow. Can you all hear me? OK. How's that for the correct level of disturbingly loud? Is that about right? OK. Excellent. So thank you all very much for coming along in your lunch break to hear me talk about things to see and hear in the fourth dimension. My name, as Allen very kindly said, is Matt P... Read More

Key Insights

• 📣 Testing the domino calculator involved precise gap strategies and trust in gaps to prevent mishaps.
• ✍️ The discovery of the hyper-diamond in 4D platonic solids fascinated Matt during the book-writing process.

Questions & Answers

Q: How did the domino calculator testing process unfold, and were there any memorable mishaps?

The testing involved constructing the calculator on concrete floors with specific gap strategies to prevent accidental triggers. There were occasional mishaps, and the rule was to trust the gaps and walk away if dominoes fell by mistake.

Q: What was the most surprising discovery during the book-writing process?

The discovery of the hyper-diamond, a 4D platonic solid, only present in four dimensions, was astonishing. The unique properties of shapes in higher dimensions intrigued Matt.

Q: Could DNA be engineered to create a knot similar to the 1011 knot for experimentation?

While the concept is intriguing, the complexity of DNA's natural coiling and enzyme interactions may complicate replicating simple knots like the 1011 knot for experimentation.
