Hedy Lamarr developed frequency-hopping, the forerunner of spread-spectrum communications used in WiFi, GPS, and Bluetooth, to control torpedoes in a way that avoided jamming by the Nazis, from her understanding of George Antheil's symphonic use of pianola rolls to synchronise multiple player pianos.

My wife said to me yesterday "How do I use a QR Code?". Keep in mind, she's a civil engineer and one of the smartest people I know. I said "In what context?" because really, I didn't know either. "I have to scan this QR code if I go to my office. It's apparently posted at the door, and will let them know I've been there, for contact tracing." After a lot of playing around, we finally found out her phone's camera coul…

It sounds like you aren't a fan of the way this QR code was used. I went to a restaurant the other day and it had one of those Coke Freestyle soda machines. There was a QR code on the screen which I scanned with my phone. This opened a website with drink choices. I put my cup under the dispenser and pushed the Barq's Root Beer button on the website on my phone which dispensed the drink from the machine. I was impress…

To me, this seems like a much more fragile and convoluted process than just having the buttons be on the machine itself. For one thing, the machine becomes unusable if there's any disruption to the network (wifi outage, dns issues, server maintenance, etc).

I'm not sure your question is correct given your premise.

Is the breadth of knowledge related to cross domain discoveries?

I would say bringing narrow skills like management or IT or marketing to a company is what you want to aim for.

I'm not convinced cross domain issues exist at rates higher than internal domain issues. I think they are orders of magnitude lower.

Frances Arnold, 2018 Nobel laureate for Chemistry, pioneered the use of directed evolution, which she conceived as an iterative lab process, to create enzymes with improved and/or novel functions, e.g. bacteria that produce the biofuel isobutanol.

That's not really an unrelated field - thats just bioengineering and synthetic biology. Thats one of the more chemistry related chemistry novels in recent times actually, since the lack of a biology nobel has led to so many biology breakthroughs getting shoved into chemistry instead that its become a bit of a running joke. This year is no exception with CRISPR being looped under chemistry even though it woupd make th…

Yes, it is bioengineering. What Arnold brought to synthetic biology is an engineer's approach to iterative process. Rather than designing a new enzyme at the molecular level, Arnold constructed a process that would yield the design for her.

Yes - but that's not interdisciplinary in the way you think it is. Designing a new enzyme at the molecular level is basically still not a thing that humans have figured out how to do. Her approach was revolutionary in the same way that the invention of a telescope was revolutionary to physics. You could try and say it was some grand synthesis of optics and astronomy, but that's a hell of a stretch, they're both physics. Evolution is just biology, and directed evolution is bioengineering. If you wanted to claim that Arnold invented modern bioengineering and laid the framework for synthetic biology, I could buy that. Just like the telescope laid the foundation for modern astronomy. But saying it's a perspective from an unrelated field doesn't make sense when it's one of the foundational defining cornerstones of this field.

Wouldn’t pressing a button on a machine be easier?

Normally I would completely agree, but perhaps in covid times it can prevent people from leaving germs on the buttons??
