How did the sauropods—the long-necked dinosaurs like Apatosaurus, Brachiosaurus, and Diplodocus that grew to be the largest land animals that ever lived—get so huge? The full answer to that question is complicated and interesting, involving a lot of science I don’t know. Come to think of it, the true answer involves a lot of physics I don’t know: calculating the compressive strength of bones, the fluid dynamics involved in getting blood from the heart up to the head, and so forth. So, I’ll leave unabashed sauropod snuggler Brian Switek to talk about the biological and reproductive aspects of the big dinosaurs, and address another hypothesis: that Earth’s gravity was noticeably weaker in the Mesozoic Era, the Age of Dinosaurs. …more

(Phys.org) —Space researchers in Japan working at the Suzaku observatory have found possible evidence of the existence of a toroidal magnetic field surrounding the magnetar 4U 0142+61. In their paper published in the journal Physical Review Letters, the research team describe their observation of inconsistent pulses coming from 4U 0142+61, suggesting the presence of an external magnetic field. …more

John Worrell Keely (1837-1898) of Philadelphia was a carpenter and mechanic who announced in 1872 that he had discovered a new principle for power production. The vibrations of a simple tuning fork had given him the idea, and the means to tap etheric energy.
Isaac Newton compared the acceleration of the moon to the acceleration of objects on earth. Believing that gravitational forces were responsible for each, Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth’s center from the object’s center. But distance is not the only variable affecting the magnitude of a gravitational force. Consider Newton’s famous equation…
NASA – NASA Chat: The Moon’s Earth-like Core
State-of-the-art seismological techniques applied to Apollo-era data suggest our moon has a core similar to Earth’s. Uncovering details about the lunar core is critical for developing accurate models of the moon’s formation. The data sheds light on the evolution of a lunar dynamo – a natural process by which our moon may have generated and maintained its own strong magnetic field.

My interest in John Keely has been solely in his research activities and how we could duplicate his experiments and demonstrations to produce similar phenomena. I did visit the site where his lab USED to be in Philadelphia and where he used to live, but nothing remains of the lab except a trashed lot. As time goes on, ever more information gets lost or destroyed.

Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles?
The experiment was conducted by Thomas Young and is known as Young’s Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment.
The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach.
Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young’s lecture and the University of Sydney for lending the double slits.
