The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time.

Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion.

Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness.

Mars InSight will be the first to detect seismic activity on Mars’ surface, first to measure rate of heat transmitted from interior, first to dig nearly 5m down, first to measure magnetic fields on Mars’ surface, and first to use a robotic arm to place instruments on the surface of Mars (assuming it lands of course…)

Following on from Canto Ostinato XL earlier this year, Brilliant Classics is proud to present Canto Ostinato XXL, a recording that brings a new perspective to Simeon ten Holt’s minimalist composition by adding a Romantic organ to the work’s original scoring for four pianos – a combination never before attempted. The result is the most beautiful and harmonious of sounds, one that captures Canto Ostinato’s emotional variety and depth through building on the sweetness and simplicity that inhabit this acclaimed composition, first performed in 1979.
Canto Ostinato is all to do with time: ‘taking your time, passing time, making time,’ as Jeroen van Veen, and one of the performers on the four-disc set, explains; and this is partly effected through the artists’ decision to repeat certain of the composition’s sections (106 in total) ad lib, thus inducing a sort of alienation of the part of the listener (because of the repetition’s posterior relationship to the harmony) and creating a hypnotic effect, a regular feature of minimalist music. Recorded over the course of just one day, this four-hour arrangement slows the tempo down a little, in order to accommodate the magnificent acoustics of the Muziekgebouw Eindhoven. Joining organist Aaart Bergwerff and Brilliant Classics regulars Sandra and Jeroen van Veen, all of whom feature on XL, are the acclaimed piano duo Elizabeth and Marcel Bergmann, both experts in the minimalist genre and who also enjoy separate international careers. Jeroen van Veen chairs the Simeon ten Holt Foundation, dedicated to keeping the wonderful music of this late Dutch composer alive.

The total solar eclipse from Madras, Oregon on August 21, 2017. As the moon passed in front of the sun turning day to night and revealing the sun's corona, apparently all I could think to say was 'Oh my goodness!'

Everyone says not to photograph your first solar eclipse and I think they might be right. I was focused on getting the exposure right for Bailey's beads and the diamond ring, plus making sure to get the corona and solar flares. This was a bit stressful but I'm delighted with the results.

This video originally included more info but since I'm uploading from Madras where the internet is sluggish, I cut out three minutes so the upload would happen before I had to leave for my flight.

Special thanks also to Dr. Teagan Wall for sharing this experience with me and Raquel Nuno for inspiring me to come to Oregon.

A trip to #Mars involves radiation, muscle and bone loss, intermediate axis theorem and liquids.
Check out Mars on National Geographic, Monday Nov 12 at 9/8c
#sponsored

When I got offered the chance to fly in another #zeroG plane, I jumped at the chance. Do you know how hard it is when you are thrust into low-gravity, like the 37% of Earth's gravity of Mars, and you have to remember what you were going to say in a 30 second window as blood floods your head? It's pretty hard. It would be even harder to actually travel to Mars. It would take about 8 months in microgravity during which time your muscles and bones would weaken substantially, even if you exercise for hours a day like the astronauts on the space station. And your heart is a muscle too so it weakens as well. Before I contemplated these rates of muscle and bone loss, I thought the major challenge with a round trip journey to Mars would be the logistics of spacecraft and having enough fuel to get back. But with the weakening of the human body, it's an open question whether anyone would really want to come back.

The aurora borealis or northern lights is one of the most spectacular natural displays on the planet. Theories about its origins have been debated for centuries and common misconceptions persist that the aurora is the sun's rays scattered off ice crystals in the high atmosphere. In truth, the light is created more than 100km above Earth's surface as high speed electrons and protons ejected from the sun in a solar flare or coronal mass ejection collide with air molecules in the upper atmosphere. The charged particles from the sun excite air molecules which then de-excite by emitting light. The display is most common around the north and south poles because the Earth's magnetic field deflects the solar wind from the equator to the poles. Here the magnetic field dips towards the Earth's surface, channeling the charged particles into the atmosphere.

I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: https://starbucks.app.link/derekmuller

Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.

Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.

A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.

Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.

It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

More Information:

Artist: Ensemble Seicentonovecento, Flavio Colusso (conductor)

Today Mascagni is best remembered for his verismo opera Cavalleria rusticana, a work which firmly belongs in many of the greatest opera houses’ core repertory, but his Messa di Gloria – which predates this composition by a matter of months and from which many of Cavalleria’s themes in fact derive – was also greatly lauded in its day. Mascagni’s interest in church music can be traced back to the days of his gifted adolescence: by the age of 13 he has written a Kyrie; at the age of 16 he refers in a letter to his involvement in composing a Mass (together with his friend Barbini); and during his student days in Milan he composed a motet as well as a great deal of music for the Messa per la festa di Maria SS. del Rosario. First performed in the Apulian town of Cerginola and conducted by the composer himself, a contemporary account of the Messa di Gloria described it as ‘a very powerful and original work, full of beauty, inspired by the requirements of modern taste’. In 1891 Mascagni repeated the peformance to an audience of 6000, as part of the celebrations marking the sixth centenary of Orvieto’s famous cathedral; such was the reception that the magazine Teatro illustrato declared the occasion ‘an event for the art of music in Italy’. Anyone expecting to hear a chorale, a fugue or even a simple fugato anywhere in the piece would have been disappointed, however, and doubts were raised regarding the religious nature of the work.

Instead, as the composer himself wrote, the Messa di Gloria can be described as a ‘prayer. The Mass is a prayer, all love and all passion!’ Here it is performed with aplomb by Ensemble Seicentonovento, an internationally renowned vocal-instrumental group that has recorded widely and appeared with such notable singers as José Carreras and Patrizia Pace. Iorio Zennaro and Pietro Spagnoli contribute well-executed arias to the mix as the respective tenor and bass soloists.

Johann Sebastian Bach’s stature as a composer of extraordinary talent and widespread influence is so firmly established in Western culture that it is difficult to believe that only 150 years ago his works lay in veritable obscurity, unknown to all but a small group of scholars. It is largely thanks to ohn, who essentially effected a revival of the composer’s music through his rediscovery and promulgation of the St Matthew Passion, besides other pieces, that his works are today regarded as pinnacles of music expression. That they are among the most performed and widely attended is in no doubt; in Holland alone, thousands of singers and musicians are involved in dozens of performances of the St Matthew Passion in Holy Week, with hundreds of thousands listening in churches and concert halls, or gathered around the radio, to what has been described as ‘the Gospel according to Bach’.

The collection Contains 142 CDs (112 hours) representing the entirety of Johann Sebastian Bach’s oeuvre in historically informed performances. This includes all 200 sacred cantatas recorded for Brilliant Classics on period instruments and sung by the Holland Boys Choir.

For this video I went off the coast of South Australia to an island frequented by great white sharks. Here they hunt seals and fish. I've never been scuba diving before but I got into a cage and filmed the sharks under water. It was an incredible experience. Then we came back on the surface to tag the sharks.
