Atlanta tinting company, The Tint Guy, would like to discuss some of the benefits of getting your commercial tinting done in the off season.

In antiquity, Pb was a common element added in the production of large bronze artifacts, especially large statues, to impart fluidity to the casting process. As Pb does not form a solid solution with pure Cu or with the Sn–Cu alloy phases, it is normally observed in the metal matrix as globular droplets embedded within or in interstitial positions among the crystals of Sn-bronze (normally the α phase) as the last crystallizing phase during the cooling process of the Cu–Sn–Pb ternary melt. The disequilibrium Sn content of the Pb droplets has recently been suggested as a viable parameter to detect modern materials [Shilstein, Berner, Feldman, Shalev & Rosenberg (2019). STAR Sci. Tech. Archaeol. Res. 5, 29–35]. The application assumes a time-dependent process, with a timescale of hundreds of years, estimated on the basis of the diffusion coefficient of Sn in Pb over a length of a few micrometres [Oberschmidt, Kim & Gupta (1982). J. Appl. Phys. 53, 5672–5677]. Therefore, Pb inclusions in recent Sn-bronze artifacts are actually a metastable solid solution of Pb–Sn containing ∼3% atomic Sn. In contrast, in ancient artifacts, unmixing processes and diffusion of Sn from the micro- and nano-inclusions of Pb to the matrix occur, resulting in the Pb inclusions containing a substantially lower or negligible amount of Sn. The Sn content in the Pb inclusions relies on accurate measurement of the lattice parameter of the phase in the Pb–Sn solid solution, since for low Sn values it closely follows Vegard's law. Here, several new measurements on modern and ancient samples are presented and discussed in order to verify the applicability of the method to the detection of modern artwork pretending to be ancient.

There's a behind the scenes industry that helps big brands decide questions like: How big should a bag of chips be? What's the right size for a bottle of shampoo? And yes, also: When should a company do a little shrinkflation?

From Cookie Monster to President Biden, everybody is complaining about shrinkflation these days. But when we asked the packaging and pricing experts, they told us that shrinkflation is just one move in a much larger, much weirder 4-D chess game.

The name of that game is "price pack architecture." This is the idea that you shouldn't just sell your product in one or two sizes. You should sell your product in a whole range of different sizes, at a whole range of different price points. Over the past 15 years, price pack architecture has completely changed how products are marketed and sold in the United States.

Today, we are going on a shopping cart ride-along with one of those price pack architects. She's going to pull back the curtain and show us why some products are getting larger while others are getting smaller, and tell us about the adorable little soda can that started it all.

By the end of the episode, you'll never look at a grocery store the same way again.

Princeton's 'extremely supportive' environment for new ideas laid the foundation for an aha moment about a toggle switch in the fruit fly brain. Do humans have one, too? 

Ahuna Mons is a volcano that rises 13,000 feet high and spreads 11 miles wide at its base. This would be impressive for a volcano on Earth. But Ahuna Mons stands on Ceres, a dwarf planet less than 600 miles wide that orbits the Sun between Mars and Jupiter. Even stranger, Ahuna Mons isn't built from lava the way terrestrial volcanoes are -- it's built from ice.
