Two dogs explain the different types of chemical bonds that form between elements.
My one suggestion for improvement is that the partner to a ‘cation’ should be a ‘dogion’ instead of the traditional ‘anion’.

Even though we were on the fringes of Hurricane Sandy, a massive pine tree in our backyard toppled over during the night, even though there was not much wind. We did not even hear it falling, suggesting that it fell over slowly rather than come crashing down, presumably because the cause was the soil being weakened by steady, but not heavy, rain rather than high wind. Fortunately it missed our house and garage and the neighbor’s house and garage and the main damage it caused was to the fence separating our two properties and to a smaller tree that was in its path.

Lindsey Stone, a 30-year old employee at a nonprofit organization in Massachusetts that assists adults with learning disabilities, was on a work-related trip to Washington DC and while there her supervisor took a photograph of her near the Tomb of the Unknown Soldier making a mocking gesture. She then (as has now become almost obligatory) posted the photo on her Facebook page. [Read more…]
The big discussion after the election has been the seemingly sudden realization by the Republican party that they need to do something about the fact that they are losing the minority vote, especially those of Latinos, big time. What is really shocking is that they did not realize this sooner, given that all the signs were there for some time. [Read more…]
I am a fan of Alfred Hitchcock films and so was intrigued by news of the film Hitchcock that centers around the time he made the classic Psycho. It has just been released, to mixed reviews unfortunately, despite the presence of excellent actors Anthony Hopkins and Helen Mirren. Here’s the trailer. [Read more…]
One man set out to collect 100 rejections in 100 days by asking random people what he thought were requests so unreasonable that they would unhesitatingly refuse to comply, and filming the process. He was stymied on the third day when a Krispy Kreme employee named Jackie went out of her way to accommodate him. [Read more…]
I have had numerous arguments with friends who are strong president Obama supporters over his asserting the right to kill whoever he chooses anywhere on the globe, using drones as the main weapon. These people defend such powers by saying that Obama is a good man and that they trust that he will use this power sparingly and only if he is sure that the people thus murdered are bad people and that it was necessary to kill them to ‘keep America safe’.

My post about how to distinguish real science from fake science generated some interesting comments, especially over my assertion that we have not as yet been able to come up with an unambiguous way to distinguish science from non-science, and it prompted me to post a follow-up to try and clarify it.

One of the recurring features of James Bond films is how the villains devise increasingly outlandish schemes to kill him. If you have seen the 1973 film Live and Let Die which I reviewed here, you will recall the scene in which he is left standing on a tiny island surrounded by a moat containing crocodiles who can easily climb onto the island. The villains then leave him, presumably because they have other pressing things to do like iron their socks or something, and so miss Bond escaping by using three crocodiles as stepping stones, running over them to get to the safety of the other bank.

One of the remarkable things about science is that it works. It produces results that are repeatable, testable, and useful. So what is it about this enterprise that we call science that makes it so successful? Philosophers and historians of science have struggled for over a century to answer this question and the related question of how to distinguish science from non-science (the well-known ‘demarcation problem’), and have basically come up empty.
