Oh, No!

November 12, 2020

It’s not just the globe; it is the whole universe!

Astronomers at Ohio State University have taken the mean temperature of cosmic gas at different distances and ages, and found that it’s roughly 10 times hotter today than it was 10 billion years ago.

Here’s the link at New Atlas, but I am sure it is (fill-in-the-blank’s) fault.

Celebrate Mole Day

October 23, 2020
FAQ – Laboratory16

When I was in school, I really loved chemistry.

Well, I really loved the idea of chemistry.

Chemistry makes everything work. We are chemistry.

When it came to studying chemistry, however, I always seemed to come up short. In lab when everyone’s experiment samples turned clear, mine turned red. When everyone’s experiment turned white, mine turned black. And my experience went on from there in the same vein.

I still love the idea and the concepts of chemistry. That is why I am noting mole day today. On October 23, we commemorate Avogadro’s number:

Simply put, Avogadro’s number is the number of particles in a mole. How many particles? Exactly 6.02214085774 ×10 23 mol.

See the 10 23 in the equation above?

It is named after the Italian scientist Amedeo Avogadro

Results have finally come in. The strength of cheese spans two orders of magnitude. Interestingly this is similar to the range of strengths found in metals. Vegan Parmesan is the high strength steel of cheeses while goat cheese is like your run of the mill lead alloy.

In further studies, it has been confirmed that potatoes are harder than apples which are harder than bananas.

Where was I?

September 3, 2020

I always wondered where my town was when the dinosaurs walked the earth, when the Rockies were built, when the sea covered the middle of North America, etc.  This interactive map designed by a paleontologist answers those questions.

I could not get the interactive map to load, so go here to see where your city was 400 million years ago:  https://dinosaurpictures.org/ancient-earth#240

Inspired by a fascination with old, illustrated medical and other scientific textbooks, artist Michele Volpi turned his skills to the medium of tattooing.  Here are some examples of finely detailed designs.

Animal, vegetable or mineral . . .

In an enchanting new video titled “Waiting to Be Found,” Dan Hoopert dives into the details within Earth’s minerals. The United Kingdom-based designer highlights the sprawling crystallization process as it expands within each deposit and alters its colors. One piece even grows a sparkling mass off its left side.

Hoopert’s project is based on a 2019 article in Earth, which states that the International Mineralogical Association recognizes more than 5,000 distinct minerals, including well-known silicates and carbonates that are frequently found in masses around the world. “Most are documented based on just a few known occurrences. It’s unlikely that scientists will stumble across many new finds of singularly abundant minerals on Earth, but numerous rare minerals are probably yet to be discovered,” the article says. In the last decade, about 1,000 new species were added to the association’s growing list.

The designer brought the project to life using 3D special effects software Houdini and Redshift. For more of his imaginary explorations of natural processes, follow him on Instagram and Behance.

There will be no “Boaty McBoatface” – Polar research ship RRS David Attenborough fires up for the first time

The British Antarctic Survey’s (BAS) polar research vessel RRS Sir David Attenborough came a step closer to going into service this week as its power systems came online for the first time and its advanced lifeboats were commissioned. In the final stages of construction at the Cammell Laird shipyard in Birkenhead, UK, it’s the first British ship that is International Maritime Organisation Polar Code-compliant.

Named after the famed nature documentary maker, the floating laboratory RRS Sir David Attenborough caused some amusement in 2016 when an invitation for the public to name it resulted in the winner being Boaty McBoatface. Now sporting a more dignified moniker, the Attenborough replaces the RRS Ernest Shackleton and RRS James Clarke Ross. When it enters service, it will carry 60 scientists and support staff in BAS operations in both the Antarctic and the Arctic. It’s 129.6 m (425 ft) long, 25 m (82 ft) abeam, has a draft of 7.5 m (24 ft), displaces 12,790 tonnes (14,098 tons), and has 4,200 m³ (148,000 ft³) of cargo space.

As part of the completion process, the lifeboats for the Attenborough have been commissioned. Each of these can carry 90 people and they are situated on both sides of the ship on specially designed davits. Based on data from previous Arctic lifeboat search and rescue expedition trials, the lifeboats and their davits can operate at temperatures down to -35° C (-31° F).

In addition, this week saw Cammell Laird engineers bringing the Attenborough’s power systems up to 100 percent for the first time. The ship runs on a hybrid system with two six-cylinder and two nine-cylinder Rolls-Royce Bergen diesel engines powering the generators, which run through a series of battery banks to provide constant loads to the electric propulsion motors and the ship’s systems. According to BAS, having engines of different sizes allows for more efficient operations under different conditions. They also run on low-sulfur fuels and are fitted with a Selective Catalytic Reduction (SCR) system to keep down emissions.

The hybrid system allows the Attenborough to break its way through ice packs a meter thick at a speed of three knots (3.5 mph, 5.6 km/h). Additionally, by using electric motors and engines sitting on rubber noise-damping pads, the ship minimizes noise to both protect the local sea life and avoid interfering with the onboard acoustic and seismic instruments.

“This is a great moment in the final stages of the build,” says John Drummond, Project Director at Cammell Laird. “Testing power and installing lifeboats are very visible signs of the huge amount of technical and engineering work that has been undertaken. This truly unique ship is state-of-the-art and highly complex – we are proud to be getting it ready for sea.”
