Periodic table: Scientists propose new way of ordering the elements New proposal The latest attempt to order elements in this mannerwas recently published in the Journal of Physical Chemistryby scientistsZahed AllahyariandArtem Oganov. Their approach,building on the earlier work of others, is to assign to each element what’s called a Mendeleev Number (MN). There are several ways to derive such numbers, but the latest study uses a combination of two fundamental quantities that can be measured directly: an element’s atomic radius and a property calledelectronegativitywhich describes how strongly an atom attracts electrons to itself....

Someone recently told me it takes 21 days to form a habit. If you want to take up running, or fitness, or a diet, there seems to be a psychological tipping point after 21 days where something becomes a habit. Interupt this new rhythm too early and the habit won’t take. Malcolm Gladwell, in his bookOutliers, argues that it takes 10,000 hours to become an expert on anything: “Gladwell repeatedly mentions the “10,000-Hour Rule”, claiming that the key to success in any field is, to a large extent, a matter of practicing a specific task for a total of around 10,000 hours....
In the short time since NASA’s Perseverance rover landed in Mars’ Jezero Crater on Feb. 18, 2021, it’s already made history. At the moment, Mars and the Earth are on opposite sides of the Sun, and the two planets cannot communicate with each other. After working nonstop for the past 216 Martian days, the science teams are taking the first real break since the mission started. We aretwomembersof the Perseverance team, and with the roverhunkered downfor the20 days of conjunction, it is the perfect time to step back and reflect on the mission thus far....
