Space is exciting so it is easy to get sucked into bold claims.
A few years ago one of our writers had the idea to launch Bloggy into space
. He was going to do all the work and just needed the money to pay the company, Interorbital, a very reasonable-sounding amount, so it was on.
My only real question was, "The knock on these guys is that they keep cashing checks but they never actually launch anything. What makes you think they will this time?"Bloggy in spaaaaace.
Windows 10 build 9926 has been with us for 53 days, or almost two months. While faster releases would be nice for those of us who don't mind bugs, it gives us an idea that Microsoft is going to release something that looks 99.9% like this build in the end. My opinion after looking at this OS and using it as a daily driver on my Surface Pro 3 while teaching and researching is that it is the OS of the future in many ways. In the future we will not interact with our computers by mouse and keyboard. That future is finally becoming technically possible. If other OS's don't evolve to deal with this shift then they will be left in the dust.
The Indian Space Research Organisation (ISRO) has successfully conducted a test on Saturday Mar. 14th to check the GSLV Mk III launch vehicle’s indigenous cryogenic CE-20 engine at ISRO Propulsion Complex (IPRC) in Mahendragiri, Tirunelveli district.
“It is yet another milestone achievement on the road map of developing a bigger and more powerful indigenously built high thrust cryogenic upper stage for GSLV Mk III rocket for the Indian Space Program,” said IPRC Director D. Karthikesan. IPRC is called the "Jet Propulsion Laboratory of India" as all stage and engine related tests of ISRO's launch vehicles and satellites are carried out there.
Two photonic properties - spin and OAM1- have been teleported together for the first time ever. The breakthrough was achieved by Chaoyang Lu, Jian-Wei Pan and their team at University of Science and Technology of China, Hefei.
The team teleported the composite quantum states of a single photon encoded in both its spin and OAM1. For successful teleportation, three entangled pairs of photons were used.
The entangled pairs were created by the usual method of shining a strong UV pulsed laser on three non-linear crystals.
A research team from University of Leeds has figured out a way to kill cancer cells photothermally. They used Near-Infrared (NIR) to heat up gold nanotubes, and, a single-wavelength pulsed laser beam to rapidly increase the temperature near the nanotubes. This focussed, high-intensity heating kills the cancer cells.
A big advantage of the method is that NIR light has maximum penetration in the tissue without much harmful consequences. To minimize toxicity further, the gold nanotubes were coated with PSS - poly(sodium 4-styrenesulfonate).
The team is led by Steve Evans of the School of Physics and Astronomy.
Two things that have caught my attention recently.
The first concerns trapping solar energy. One way to do this is to convert it directly into electricity with a solar panel, but one with much wider application would be to split water into oxygen and hydrogen, which can then be stored and transported.
An international team of physicists have been able to reconstruct the first ever 3-D image of individual virus particles by tweaking the X-ray diffraction technique of nanocrystallography1
Cleverly bypassing the tedious procedure of crystallizing individual particles, the researchers targeted the virus (Acanthamoeba polyphaga mimivirus) with high-energy pulses (70 fs duration) from an X-ray free electron laser. The X-rays scattered from the virus bodies, creating a 2D diffraction pattern.
Using 200 such different patterns and a mathematical algorithm to solve the problem of particle orientation, a single 3D electron density image was produced.
Sometimes science is the only witness to a crime.
Fortunately, the application of scientific evidence in criminal proceedings has grown in proportion to the availability of cutting-edge methods and technologies that can produce answers to critical questions related to guilt or innocence.
Scientific evidence, of course, is a good thing, provided that our courts do their due diligence to ensure that the testimony of expert witnesses and the observations, data, and interpretations upon which they are based are reasonably valid.
In a previous blog post, I demonstrated how to build a magnetic optical mount for a laser using Erector set parts
. Here's another method of attaching a chip clip to the Erector set stand.
Erector set right angle bracket 3-hole (mine is a bit more than 90°)
Erector set nut
Computer case thumbscrew
I used a knife to cut a slit in the rubber grip of the chip clip just wide enough for the Erector set angle bracket to fit tightly once inserted in the grip.
I like to think of myself as a researcher who focuses on both pain and addiction. Honestly, I may never have an actual career in academic science because there is only a 1 in 5 chance of that happening. I always wanted to teach, but realize there is a slim chance of that ever happening, especially since the University system has been turned into a complete joke by administrators. That is why I like the idea of Science 2.0 and blogging because I can provide knowledge, as if teaching, in a short missive. I apologize for the recent spate of pieces, but I have been busy studying yawning in rats. That’s right Tom Coburn, yawning in rats!
