I guess the funniest thing I ever saw was a person driving down the highway in a Toyota Prius smoking a cigarette with the windows closed. It was like they were telling me, “I respect your atmosphere but not mine.” That got me thinking, does human generated, gaseous, atmospheric pollution actually make up a significant part of the total atmosphere, and can it possibly affect it?
Philosophers of science are in the business of explaining the special features of science, like the unifying power of scientific explanation and the wonderful sense of understanding it produces. We try to explain the amazing success of modern scientific theories, the structure of inductive inference in the science, and extract systematic positions – like realism, constructivism, and empiricism – from the evidence of theoretical success.
Whilst learning about the planets in our Solar System, and then hearing all that has befallen them in the news over the past decade, have you ever wondered which one you might best get on with? Or which planet you would be? We certainly have, which is why we’ve created the quiz below, to help you find out.
Proving to be both varied and fascinating, moons are far more common than planets in our Solar System. Our own Moon has had a profound influence on Earth, not only through tidal effects, but even on the behaviour of some marine animals. But how much do we really know about moons?
Golf balls curve in flight for one principal reason: Namely that the golf club face is not square to the path being followed by the club head as it impacts the ball. This is illustrated in the figure where the club face is “open” to the club path by about four degrees. This is sufficient to produce a significant slice to the right.
When people think of evolution, many reflect on the concept as an operation filled with endless random possibilities–a process that arrives at advantageous traits by chance. But is the course of evolution actually random? In A World from Dust: How the Periodic Table Shaped Life, Ben McFarland argues that an understanding of chemistry can both explain and predict the course of evolution.
Einstein has had a good month, all things considered. His century-old prediction, that the very fabric of space and time can support waves travelling at light-speed, was confirmed by the LIGO collaboration. More, the bizarre and horrifying consequences of his theory of gravity, the singularly-collapsed stars that came to be called ‘black holes’, have been directly detected for the first time.
What was our solar system composed of right after its formation? Using sophisticated computer simulations, researchers from France and Australia have obtained new insights into the chemical composition of the dust grains that formed in the early solar system which went on to form the building blocks of the terrestrial planets.
The remarkable detection of gravitational waves by the LIGO collaboration recently has drawn much attention to the fundamental and intriguing workings of gravity in our universe. Finding these gravitational waves, inferred to be produced by merger of two stellar mass black holes, has been like listening to the very distant sound of the universe.
This blog post concerns a virtually unknown chemist, John David Main Smith, who contributed a significant piece of research in atomic physics in the early 1920s at the time when knowledge of the field was undergoing very rapid changes. Main Smith is so little known that I had to search far and wide for a photograph of him before finally obtaining one from his son who is still living in the south of England.
In Rome on 22 June 1633 an elderly man was found guilty by the Catholic Inquisition of rendering himself “vehemently suspected of heresy, namely, of having held and believed a doctrine which is false and contrary to the divine and Holy Scripture”. The doctrine in question was that “the sun is the centre of the world and does not move from east to west, that the earth moves and is not the centre of the world.
Does this even make sense? Doesn’t quantum mechanics involve advanced esoteric mathematics? Didn’t Richard Feynman say that nobody understands quantum mechanics, and Niels Bohr remark that those who aren’t shocked by quantum mechanics can’t possibly have understood it?
Mary Somerville: the new face on Royal Bank of Scotland’s ten-pound note is worthy of international recognition
From 2017, ten-pound notes issued by the Royal Bank of Scotland will feature a new face: that of the great nineteenth-century science communicator Mary Somerville. Her book on mathematical astronomy, Mechanism of the Heavens — published in 1831, when she was fifty years old — was used as an advanced textbook at Cambridge for a hundred years. This is a phenomenal achievement for a woman who taught herself science and mathematics.
We are living with a climate system undergoing significant changes. Scientists have established a critical mass of facts and have quantified them to a degree sufficient to support international action to mitigate against drastic change and adapt to committed climate shifts. The primary example being the relation between increased atmospheric carbon dioxide concentrations and the extent of warming in the future.
The discovery of gravitational waves, announced on 11 February 2016 by scientists from the Laser Interferometer Gravitational-wave Observatory (LIGO), has made headline news around the world. One UK broadsheet devoted its entire front page to a image of a simulation of two orbiting black holes on which they superimposed the headline “The theory of relativity proved”.
During the search for scents of anger and aggression in human beings, several English idioms come to mind relating aggression to odors: ‘To be incensed’ describes somebody feeling angry with the related meaning of the word incense, a substance that produces a strong smell when burned.
