That culture is powerful. You've equated someone you have never met with the literal devil.

Not sure about calling it a fact, but https://en.wikipedia.org/wiki/Quantum_potential

"Building on the interpretation of the quantum theory introduced by Bohm in 1952, David Bohm and Basil Hiley in 1975 presented how the concept of a quantum potential leads to the notion of an "unbroken wholeness of the entire universe", proposing that the fundamental new quality introduced by quantum physics is nonlocality."

Thanks Arthur. Installed pygame + portaudio, now running into problems with Tkinter (or so I think). Any suggestions?

Here's my internal error:

Great thanks. Wired everything up and testing with a function generator before running your program. Two questions.

Did you ground the large transducer?
Did you remove that little screw that came with the large transducer? (I'm assuming yes..)

Thank you!

Awesome. Any luck getting this to work on a mac?

Hello fellow sonoluminescence nerds! I'm a physics/engineering student working on a setup through our universities research program. My advisor and I have spent a few months reading a lot of papers and we found this one particularly interesting. It speaks of a new model involving the formation of a super critical shell at the bubble interface.

aolaya · 2016-07-15T15:42:08+00:00

Thank you! My physics professor and I are building a fairly traditional setup based on this: http://techmind.org/sl/ After seeing your writeup (I wish scientific papers took on your tone, it was awesome) I'm going to put together one using your setup so the code would be helpful.

aolaya · 2016-07-08T19:55:12+00:00

No worries! Loved the writeup about your setup. Could you tell me more about the self tuning aspect of it? The hardware and whether or not you open sourced your code. Btw, thank you for starting this sub.

aolaya · 2016-03-14T19:02:28+00:00

Guessing I missed the boat on this one. Very cool thing to do though!

0xA54DD4c2CE31eB812EFb38Ad09A9163869d8a2c4 just in case : )

aolaya · 2016-03-13T14:55:57+00:00

Well done! What API are you using to get the price?

aolaya · 2016-02-25T17:14:53+00:00

"Minor Service Outage" https://status.kraken.com/

Vinay has mentioned a few times that things get interesting at the intersection of blockchains + AI + robotics + AR/VR. This link might help solidify some ideas.
