Between a supply chain full of holes, labor shortages across various sectors of the economy, and rising inflation, it’s shaping up to be a somewhat chaotic holiday season. Technology can’t fix all of these problems—or even most of them—but it can help get holiday shipments from point A to point B faster, cheaper, and without as many humans involved. Waymo’s partnership with UPS could mean some of your holiday gifts will be spending time in an autonomous truck on their way to you.

Waymo (which started out as the Google Self-Driving Car Project in 2009 and is still held by Alphabet, but raised $2.5 billion in its first outside funding round in March of 2020) first announced a partnership with UPS in January 2020, in which Waymo Driver was used to help move packages between UPS stores in Phoenix and the UPS hub in Tempe. Waymo’s Chrysler Pacifica minivans drove autonomously, but trained operators were on board to monitor the vehicles.

Last week the two companies announced an expansion of their existing partnership, saying they’ll start autonomous trial runs using Class 8 trucks equipped with the fifth-generation Waymo Driver. They’ll do deliveries for UPS’s North American Air Freight unit between facilities in Dallas-Fort Worth and Houston. Waymo’s initial route for its driverless cargo shipments also ran between Houston and Fort Worth, which the company said is one of the most highly utilized freight corridors in the country. The route is around 260 miles long, much of that a straight shot on Interstate 45.

[Cross posted on Chi-Ning’s blog, the course is open also to non-Harvard people. Chi-Ning is my amazing grad student, who has worked on several aspects related to the course, including quantum computation and neurally-plausible computation. He assembled a great collection of guest speakers and so this course looks like it will be very exciting. Boaz]

In the following January, Harvard GSAS kindly supports me to offer a mini-course on “What is Computation? From Turing Machines to Blackholes and Neurons”. In this blog post, I’m going to share the motivation for teaching this mini-course and give an overview on what you will learn if you are interested in participating!

Computation is not an exotic word for people living in the 21st century. In high school, kids have to learn and do all sorts of computations in arithmetics (and some even start to write computer programs!). For scientists, computational methods become more and more common and sometimes even completely change the paradigm of a field. There are computers of different forms hiding in our daily life ranging from your smartphones to the toy of your pets. Also, from time to time we see excitement on the news about the development of quantum computing and artificial intelligence. Computation has become central in human civilization, however, do we really understand what computation is?

You’ve probably heard that NASA’s Parker Solar Probe made history this year by becoming the first spacecraft to “touch the Sun.” Now there’s video of the probe whizzing through the Sun’s corona, and to say it’s breathtaking is an understatement of the year. And yes, that is the Milky Way, as seen through the Sun’s “atmosphere”, special guest starring.

Parker is no stranger to historic firsts and record-breaking feats. It broke the distance record this year, becoming the closest human-made object to the Sun at only 8.5 million kilometers (5.3 million miles) from the Sun’s surface. It also broke its own record, making it the fastest man-made object ever.

Its latest historic milestone, however, comes with video footage. Take a ride through the Sun’s corona, Milky Way and all.

Summary: A new theory suggests consciousness is a state tied to complex cognitive operations, and not a passive basic state that automatically prevails when we are awake.

Two researchers at Ruhr-Universität Bochum (RUB) have come up with a new theory of consciousness. They have long been exploring the nature of consciousness, the question of how and where the brain generates consciousness, and whether animals also have consciousness.

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape.

The researchers envision new possibilities for self-powered communications, sensing, and computational devices that could be worn like ordinary clothing, as well as devices whose batteries could also double as structural parts.

In a proof of concept, the team behind the new battery technology has produced the world’s longest flexible fiber battery, 140 meters long, to demonstrate that the material can be manufactured to arbitrarily long lengths. The work is described today in the journal Materials Today. MIT postdoc Tural Khudiyev (now an assistant professor at National University of Singapore), former MIT postdoc Jung Tae Lee (now a professor at Kyung Hee University), and Benjamin Grena SM ‘13, Ph.D. ‘17 (currently at Apple) are the lead authors on the paper. Other co-authors are MIT professors Yoel Fink, Ju Li, and John Joannopoulos, and seven others at MIT and elsewhere.

NASA’s Perseverance rover landed on February 18 and Zhurong arrived a bit later on May 14. UAE’s Hope orbiter entered Martian orbit on February 9. Although all three of these missions were launched in 2020, their arrival is too significant not to count in this year’s achievements.

Billionaires, Private Space Flights

2021 could also appear as a year when you could finally believe that certain someone selling you a ticket to space is not a scam. Do not forget to fact-check their claims with the celebrity physicist Neil Tyson though. In July, when commercial spaceflight company Virgin Galactic’s top management including the company’s founder Richard Branson flew to a height of 86 kilometres, Tyson contested Virgin Galactic’s space travel claim by saying it was a suborbital flight.
