7:39 PM | “Could a Quantum Computer Have Subjective Experience?”
Author’s Note: Below is the prepared version of a talk that I gave two weeks ago at the workshop Quantum Foundations of a Classical Universe, which was held at IBM’s TJ Watson Research Center in Yorktown Heights, NY.  My talk is for entertainment purposes only; it should not be taken seriously by anyone.  If you reply in a way […]

7:11 PM | Graphene drum could form future quantum memory (w/video)
Scientists have demonstrated that they can detect extremely small changes in position and forces on very small drums of graphene. Graphene drums have great potential to be used as sensors in devices such as mobile phones.

7:00 PM | A Better Way to Build a Pyramid?
The Egyptian pyramids are some amazing works of engineering. The biggest, the Great Pyramid at Giza, held the record for nearly 3,800 years as the tallest man-made structure in the world. What's astounding is that each limestone and granite block weighing up to eighty tons had to be dragged from quarries miles away, then hoisted up to 400 feet before finally being laid in place. Two of the pyramids at Giza.

6:34 PM | The song of the black hole
Black holes sing in harmony with themselves. The “notes” are flashes of light rather than sound, but black holes born from the death of very massive stars emit bursts as hot matter orbits close to the event horizon. That’s a natural consequence of the in-and-out motion of high-energy particle motion as strong gravity whips them […]

5:41 PM | Il segreto dei cospiratori egiziani
Inizia come una spy story, Il segreto dei cospiratori egiziani, o come un fumetto noir, come afferma Baffo durante l'immancabile inseguimento sul tetto del treno in un incipit che, in effetti, sembra ispirato anche a Mistero sull'Orinet Express di Agatha Cristie.Dietro questo inizio al fulmicotone c'è una cospirazione ordita dal professor Baribari che, utilizzando il suo robot Cleopatra, cerca di riportare al suo antico splendore il Regno dell'Egitto e, da qui, conquistare il mondo […]

1:33 PM | Dewar Attenuation of Gamma Rays: Lab Book 2014_08_21
Summary:  Initial results from the Dewar attenuation tests look odd.  They won’t be conclusively odd until all the sources have been measured for the same counting time.  At the moment, the Cs 137 32 keV line is less attenuated than the 22 keV Cd 109 line which is expected, but it also appears to be less attenuated than the Cd 109 88 keV line which is not expected.  It seems like a higher energy should have an easier time getting through the Dewar material.To Do […]

9:49 AM | Nanotechnology in agriculture
Nanotechnology applications are currently being researched, tested and in some cases already applied across the entire spectrum of food technology, from agriculture to food processing, packaging and food supplements. Specifically in agriculture, technical innovation is of importance with regard to addressing global challenges such as population growth, climate change and the limited availability of important plant nutrients. Nanotechnology applied to agricultural production could play a […]

9:16 AM | A newly discovered gold nanocluster promises rich chemical yields
Researchers have found one new gold molecule, a catalyst containing exactly 25 gold atoms, that is powerful as well as sophisticated. It catalyzes the conversion of a variety of molecules, including the transformation of poisonous carbon monoxide into harmless carbon dioxide, a reaction that may find application in devices near gas flues or wood-burning stoves.
