I am sure that many readers have tried for themselves, or at least heard about, the famous experiment done in 1999 by Daniel Simons and Christopher Chabris. If you are not aware of what I am talking about, check out this video before reading on. I recommend watching the video on full screen mode.
This time of year brings an endless supply of best/worst lists most of which I ignore. The ones that I read are those of people who have died because often news of such people’s passing was lost in the noise when it happened. One such list that I read are those of actors but this one of scientists who died is also noteworthy, the most famous of whom was Stephen Hawking.
Another is this list of writers, musicians, and actors who died.
People either love or hate this film, with very few falling into the lukewarm category. I personally love it. I was blown away when I saw it when it first came out 50 years ago and watched it again a few days ago, perhaps for the third or maybe the fourth time, It as always risky to watch a film or read a book that one loved a long time ago when one was much younger because of concerns as to how well it would stand up. I watched it this time with a more critical eye and found that it stands up incredibly well and is as engrossing as ever. I enjoyed it so much that the next day I watched it all over again, this time with a commentary by actors Keir Dullea and Gary Lockwood who play the laconic astronauts Dave Bowman and Frank Poole, who discuss what it was like working with legendary director Stanley Kubrick and how some of the effects were produced. They say that he was meticulous in his preparation for filming but gave very little direction on how they should play the scenes.

John Wenz has a fascinating account of a ‘secret’ meeting of scientists held in 1961 at the Green Bank Observatory in West Virginia, which at that time was the biggest telescope available to radio astronomers. The reason it was kept hush-hush was not because they were doing anything nefarious but because these were people who were interested in seeking signs of extra-terrestrial life and that was considered somewhat fringey and they did not want to tarnish their reputations as serious scientists.

Via David Pescovitz, I came across something called the ‘morph cut’, a video editing technique that can be used to eliminate pauses, stutters, and filler words and provide for smoother-sounding interviews, unlike with a ‘jump cut’ where you can see the abrupt transition. But the catch is that if not done carefully, it can produce unexpected results, like in this clip where a child suddenly materializes behind the speaker.

When current flows in materials, it generates heat because of the resistance it encounters. This causes the materials to get hot and this has to be accounted for when designing electrical systems in order to avoid fires or meltdowns. This heat is also a major source of energy dissipation and loss. Superconductors are materials that do not have any resistance to the flow of current and thus can cut down energy consumption tremendously.

Megan Molteni has an article in Wired discussing an old problem: What do you do with scientific information that was obtained unethically? This is an old problem that has been seen in stark forms with Nazi scientists experimenting on Jewish captives prior to and during World War II and the US government experimenting on black people for four decades in the infamous Tuskegee experiments.Molteni brings this up in the context of the genetic modification done on two human embryos using the CRISPR technology. As Molteni says:

Given that the population if India is over one billion, raw numbers of almost any statistic are likely to be large. But I was still stunned to see this report that estimates that 1.24 million people were killed in 2017 alone due to the effects of air pollution, and that life expectancy was reduced by 1.7 years because of this.

Most readers of this blog would likely have heard about the charges swirling around Neil deGrasee Tyson about his behavior around women. Azeen Ghorayshi has a long piece about the allegations made against Tyson, including new claims by a fourth woman. It goes into great detail, provides a great deal more background on the rape accuser Tchiya Amet than I had seen before, and has accounts from many people other than the four women.

When in 1998 an organization called the Friends of Benjamin Franklin House decided to restore the house that Franklin had occupied while he was the American ambassador to England, workers discovered a trove of about 1200 human bones buried in the basement.
Initial reports said the bones were from the remains of more than 15 bodies — six of them children. Some of the bodies were dismembered, or with trepanned skulls (skulls with holes drilled through them).
The bones were dated to be just over 200 years old, which would mean they were buried around the same time Franklin lived in the house. So where did the bones come from? Did Benjamin Franklin, one of the Founding Fathers of the United States, kill people and hide their remains in his London basement or could there be another answer to this creepy story?
