Did you know, hops were introduced to English brewing in the 1600s by Flemish brewers emigrating to Kent from Flanders in Dutch speaking Belgium? 🍺 🌿

Bier brauen, Brot backen und Keramik brennen für die Wissenschaft vom 30.07. 01/08/2021

"Podcast" für die Interessierten 🍻🧙

Bier brauen, Brot backen und Keramik brennen für die Wissenschaft vom 30.07. Wie haben die Menschen in der Stein-, der Bronze- oder der Eisenzeit gelebt? Wie haben sie ihre Unterkünfte gebaut, das Essen zubereitet, Pfeile hergestellt, Kleidung gewebt oder Krüge gefertigt? Diesen Fragen versucht die experimentelle Archäologie auf den Grund zu gehen. Sie nähert sich aufgru...

We saw thousands of tons of ammonium nitrate explode in 2020 in Beirut, blowing through the city with a force rivaling a small nuke. A similar disaster happened a hundred years ago, with a bigger pile of fertilizer, but someone hit the ‘blow this place to kingdom come’ button on purpose.

They thought it would be fine, like it had been twenty thousand times before.

Today’s Moment of Science… the 1921 Oppau Explosion.

A BASF plant was built in Oppau, Germany in 1911 to produce ammonium rich fertilizers. They switched from ammonium sulfate to ammonium nitrate during WWI because they were having trouble getting sulfur from international suppliers. Something about a shortage. Or maybe countries wanted to avoid sending a key ingredient for chemical weapons to one of the countries spritzing mustard gas across Europe.

After the war, they produced an ammonium sulfate and ammonium nitrate mixture called ‘mischsaltz,’ or ammonium sulfate nitrate. Ammonium nitrate is hygroscopic, a quality of attracting water out of the air. Under the force of its own weight, mischsaltz could compact and harden into a cake of potentially explosive f**kery. Though workers could get at it with pickaxes, that risked the ammonium sulfate nitrate possibly shifting beneath their feet, burying them under their work.

So they chose the much safer option: blowing s**t up.

Surprisingly, this was common practice at the time. It had been observed that, below sixty percent ammonium nitrate, there was no risk of detonation. Their mixture was about 50/50 of the two substances. It was totes fine.

There were other things happening in that silo that they would eventually figure out were conducive to conflagration. A new process they used to dry the ammonium salt mixture had increased its explosivity. It was also understood that some areas of the silo had accumulated higher amounts of ammonium nitrate than others, forming a readily accessible, highly explosive dust. Leave a silo full of chemicals out to bake for a while with a quality management system involving pickaxes and dynamite, you’ll miscalculate something eventually.

On September 21, 1921, they had to gnaw off a chunk of mischsaltz. So on with the dynamite they went, as they’d done a reported 20,000 times before.

Witnesses heard two explosions, and a piece of this world was torn from existence.

Where there once was a silo, there now stood a crater twenty meters deep and over a hundred meters across.

With only about 10% of the total load detonating, it blew with the force of about 1,000 tons of TNT, not dissimilar in impact from a little nuke. The pressure wave from the explosion shattered windows, collapsed homes, even tore roofs straight off buildings as far as 25km away, with damage observed much further out than that. The explosion was said to be felt hundreds of miles away in Munich.

Estimates tend to place the death toll at 560 people, and approximately 2,000 more were injured. Most structures in the small town were destroyed, leaving 6,500 homeless. With everything and everyone involved in the accident obliterated, no firm answers on what went wrong were ever found.

They still store ammonium nitrate and ammonium sulfate together, but new technology prevents the substances from compacting. BASF’s statement on their website basically said “uuuh we stopped producing that stuff for a little while. So it’s cool, right?”

Nobody ever admitted fault.

This has been your daily Moment of Science, reminding you that there’s always another Oppau waiting.

Modelling the spread of SARS-CoV-2: How reliable are simulated forecasts? Since the worldwide outbreak of the COVID-19 pandemic, experts all around the globe are working heavily to establish reliable forecasts for the spread of the disease. Hereby they allow decision makers to roughly plan ahead and inform the population with estimates of what might still lie ahead. Yet,....

A Recipe for Disaster — How Lambic Continues to Redefine the Beer World 07/04/2019

Einfach mal zur Appetitanregung - und zur Erinnerung, dass ist ein historischer Bierstil aus Belgien 🤗

A Recipe for Disaster — How Lambic Continues to Redefine the Beer World Lambic is the closest thing we have to the ur-beer, to humanity’s batch 001. Natural inoculation—the miracle of air transforming grain and water into something more—happened right at the start of civilization. Some anthropologists even claim our nomadic species only settled down so we could cu...

Craft-Biere: Hauptaromastoff erstaunlich kurzlebig 22/01/2019

Craft-Biere: Hauptaromastoff erstaunlich kurzlebig Auch kühl gelagertes Craft-Bier hat bereits nach drei Monaten ein Drittel seines Haupt-Aromastoffes eingebüßt. Bei falscher Lagerung sogar deutlich mehr. Das ergab eine Studie an der TU München. Wer also auf das typische starke Hopfenaroma dieser Biere wert legt, sollte es möglichst frisch geni...
