Peanut butter is a liquid – the physics of this and other unexpected fluids

Published Tue, 04 Mar 2025 11:55:25 GMT

(The Conversation) - Those Transportation Security Administration requirements are drilled into every frequent flyer’s head: You can carry on liquids that are only less than 3.4 ounces (100 milliliters) in volume each.But when the TSA recently confiscated a jar of Jif under this rule, peanut butter lovers were up in arms. Some skeptics of security may suspect hungry officers just wanted to make their own PB&Js. TSA, however, contends that peanut butter is a liquid – and a full-size jar of Jif is over the 3.4-ounce limit.Just like Americans’ favorite legume-based sandwich ingredient, the story – and the outrage it inspired – began to spread. However, I’m a mechanical engineer who studies fluid flows, and the TSA action made sense to me. By the scientific definition, peanut butter is indeed a liquid.First consider fluidsTo define a liquid, we must first define a fluid. Any material that flows continuously when a shearing force is applied is a fluid. Think ...

Worries grow about Ukraine nuke plant amid evacuations

Published Tue, 04 Mar 2025 11:55:25 GMT

By DAVID RISING (Associated Press)KYIV, Ukraine (AP) — Anxiety about the safety of Europe’s largest nuclear power plant grew Sunday after the Moscow-installed governor of the Ukrainian region where it is located ordered civilian evacuations, including from the city where most plant workers live.International Atomic Energy Agency Director General Rafael Grossi has spent months trying to persuade Russian and Ukrainian officials to establish a security zone around the Zaporizhzhia Nuclear Power Plant to prevent the war from causing a radiation leak. The evacuations ordered by the Russia-backed governor of Ukraine’s Zaporizhzhia province, Yegeny Balitsky, raised fears that fighting in the area would intensify. Balitsky on Friday ordered civilians to leave 18 Russian-occupied communities, including Enerhodar, home to most of the plant staff.More than 1,500 people had been evacuated from two unspecified cities in the region as of Sunday, Balitsky said.

Sowing the seeds of death in the Caucasus

Published Tue, 04 Mar 2025 11:55:25 GMT

Ukraine will need at least a decade to clear the mines planted by the Russian occupational army in its territory. 30% of its land is dangerous to step on - writes James Wilson"Ukraine is the largest mined area in the world," the international think tank GLOBSEC said in a report published on 26 April. "Ukraine has become one of the world's largest minefields," the UN agency UNDP reported on 4 April. The report explained that "more than 14 million people" are at risk of being blown up by mines.But before Ukraine, this horrible record belonged to another country friendly to Ukraine, the soil of which is filled with hundreds of thousands, if not millions of exactly the same Russian-made mines. Moreover, their number continues to grow even today, again thanks to Russia.The country is Azerbaijan, which liberated its occupied territories of Karabakh in 2020. The separatist enclave that remains in this region, inhabited only by Armenians (after the ethnic cleansing of Azerbaijanis in the la...

Moscow’s playbook in Karabakh

Published Tue, 04 Mar 2025 11:55:25 GMT

Situated at the crossroads between the Islamic Republic of Iran and the Russian Federation, the Caucasus region is heavily influenced by these two regional superpowers - writes James Wilson.The US Secretary of State Antony Blinken hosted talks between the Armenian and Azerbaijani Foreign Ministers last week, intending to broker a lasting peace treaty between these two clashing countries. Many attempts to put the Armenian-Azerbaijani conflict to rest have been made over the years, but this is the first time that US officials have taken an active part in the negotiations. It should come as no surprise that Blinken's decision to take a much more active part in the talks comes as a result of the increasing influence of other regional powers on the parties involved. This foreign influence also happens to have a distinct anti-Azerbaijani bias, as both Moscow and Tehran hold much against Baku. A focal point in the dispute between Azerbaijan and Armenia is the Armenian-populated separa...

D. (Economics), expert on taxation at the Growford Institute.For the first time, Kyiv is reaping the benefits of its fight against endemic corruption.
