Brief items

Here are a few items I came across in the last few days that may be of broader interest:

• John Preskill's lectures for his quantum computing course (cross-listed between physics and CS at Cal Tech) are now available on youtube here.  Here are the lecture notes. 
• Christopher Gutiérrez at UCLA had previously made a very helpful set of tutorials for using Adobe Illustrator and Blender to make high quality scientific figures, and those are here.
• Here is a nice article explaining in some detail about what will be required for semiconductor fabrication (particularly the metal vias) to reach the "2 nm node" (which does not mean that minimum feature sizes will be 2 nm).  
• Along those same lines, the Semiconductor Research Corporation has released their Decadal Plan for Semiconductors.  Themes include a renewed interest in analog electronics for AI and machine learning (hello neuromorphic computing), and a critical need for new memory technologies as projected demand for memory will outstrip foundry production capacity if traditional memory architectures are followed.
• APS and AAPT have released large portions of their Effective Practices for Physics Programs guide.
• The video of the landing of the Perseverance rover on Mars is just fantastic.
