The Best Way to Drop an Egg Without Breaking It, According to Science
Here's hoping Humpty Dumpty reads the news. In research out today, scientists have apparently figured out the safest way to drop an egg without it breaking. Researchers at MIT conducted the study, published Thursday in Communications Physics. After nearly 200 experiments, the team determined that dropping an egg horizontally is more likely to keep it intact than a vertical drop—completely contrary to folk wisdom. MIT and many other schools regularly host an 'egg drop challenge' for their students. The goal is simple enough: use some ingenuity and basic materials like toothpicks and twine to construct a contraption that will keep their eggs from breaking once dropped. But according to study researcher and engineer Tal Cohen, both teachers and online sources will often also recommend that the egg stays vertical to further lower the risk of cracking. The underlying assumption behind this advice is that the egg's vertical structure resembles an arch, and arches are very good at redistributing the loads of energy (or force) placed on them. 'After a number of times doing this competition, we started to question the common notion. We weren't convinced that the static explanation, which applies to an arch, translates to the case of dynamic impact,' Cohen, an associate professor in the Sustainable Materials and Infrastructure department at MIT, told Gizmodo. Cohen and her team took some of the eggs left behind at the end of a recent MIT challenge to test their hunch in the lab, but their initial experiments were inconclusive. So they decided to start a formal and more extensive project. In total, they dropped 180 eggs either vertically or horizontally onto a hard surface. The eggs were dropped in rounds of 60 each at three different heights: 8, 9, and 10 millimeters (basically between 0.32 and 0.39 inches). And overall, the vertically dropped eggs fared worse. More than half of the vertical eggs broke when dropped 8 millimeters, for instance, compared to less than 10% of horizontal eggs. Further tests also showed that the horizontally dropped eggs could compress more before breaking than the vertically dropped ones. The findings might not be world-changing, but they illustrate how our conventional wisdom can sometimes lead us astray, even the kind that's taught in science classrooms. 'People tend to have better intuition for stiffness and strength, which are important in statics. It is common that they refer intuitively to the redistribution of a load along the arch. However, when dynamics are involved, toughness is also an important quantity,' Cohen said. 'For example, consider two balls; one made of glass, and the other of rubber. The glass ball is stiffer and may have higher strength, but when dropped from a height, the glass ball is also more likely to break, while the rubber ball can deform to absorb the kinetic energy, without breaking.' Cohen notes that there are plenty of things in both nature and engineering like eggs that have thin shells protecting their inner contents. So their research here could very well help 'influence how people think about these structures as well,' she said. Personally, I'm just glad I'll have another reason to be mad at myself when I inevitably drop my next egg onto the kitchen floor while cooking—I should have remembered to keep it horizontal!

The Best Way to Drop an Egg
The egg drop challenge is an annual rite of passage for many students learning about physics: Swaddle an egg in cotton balls and masking tape or other materials, and then drop it off the roof of your school. Anyone who has participated in this exercise knows how difficult it is to engineer a structure that will save the egg from a messy end. (It certainly was not my bespoke foam core creation in middle school.) Once the eggs are broken, teachers may reveal insights into the physics of impact, including the claim that eggs sitting vertically crack less often than eggs sitting horizontally. But is that really true? After running egg drop challenges for university freshman, Tal Cohen, an engineering professor at the Massachusetts Institute of Technology, began to wonder whether that assertion really fit the picture of a falling egg. 'It's based on the static behavior of an egg,' she said. 'Dynamic impact is quite different.' To assess whether she was telling students the right story, she headed to the lab, eggs in tow, and performed some tests. What she found suggested the truth was more complicated, and in a paper out Thursday in the journal Communications Physics, she and her colleagues report that eggs lying horizontally are actually less likely to crack. To perform their experiments, the researchers first headed to Costco and picked up more than 200 eggs (this at a moment in 2023 when eggs were cheaper than today). Then the team crushed some in a device that allowed them to record the force required to crack the shells. They found that eggshells cracked under about the same force regardless of whether they were lying down or sitting up in the device. They then actually dropped the eggs. For experimental purposes, they dropped them from tiny heights — just eight millimeters or so. That was so they could see a variety of outcomes. If they dropped the eggs from bigger heights, all of them broke regardless of orientation. An important difference between the positions was observed. Eggs dropped so they landed on their sides were substantially less likely to crack. When they hit, the shell was able to compress, absorbing some of the blow. Eggs dropped on their ends, where the shell is stiffer, did not show such flexibility. There's an analogy to be drawn to the human body, said Joseph E. Bonavia, an M.I.T. graduate student in engineering and an author of the paper. 'If you are falling from a height, you don't want to lock your knees. You'll break your bones,' he said. 'You want to bend your knees — that's what the egg is doing.' The way we cook eggs may have contributed to the widespread misunderstanding that the side of the egg is most fragile, said Brendan M. Unikewicz, also an M.I.T. graduate student and another author of the paper. That's because we usually crack eggs in half at the midpoint. Breaking the horizontal side results in long cracks that can split the shell in half cleanly, while cracking eggs on their tips, as these experiments showed, results in the shell collapsing inward — not, in other words, the optimal outcome for making an omelet. Indeed, the experiments reveal that our intuition about what happens in real-life scenarios where an object is falling cannot always be relied upon, Dr. Cohen said. This is why it is important for engineers and students of engineering to remain open to challenging conventional wisdom, she said. Did anyone eat the eggs? By university policy, humans are not allowed to consume experimental materials after they've entered the lab. But Dr. Cohen's dog, under no such prohibition, had some hearty meals.

Insiders At Nasdaq Sold US$8.4m In Stock, Alluding To Potential Weakness
The fact that multiple Nasdaq, Inc. (NASDAQ:NDAQ) insiders offloaded a considerable amount of shares over the past year could have raised some eyebrows amongst investors. When analyzing insider transactions, it is usually more valuable to know whether insiders are buying versus knowing if they are selling, as the latter sends an ambiguous message. However, shareholders should take a deeper look if several insiders are selling stock over a specific time period. While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we would consider it foolish to ignore insider transactions altogether. We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free. The Executive VP, Bradley Peterson, made the biggest insider sale in the last 12 months. That single transaction was for US$1.0m worth of shares at a price of US$75.38 each. That means that an insider was selling shares at below the current price (US$76.14). We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 8.7% of Bradley Peterson's stake. Over the last year we saw more insider selling of Nasdaq shares, than buying. You can see a visual depiction of insider transactions (by companies and individuals) over the last 12 months, below. If you want to know exactly who sold, for how much, and when, simply click on the graph below! See our latest analysis for Nasdaq If you are like me, then you will not want to miss this free list of small cap stocks that are not only being bought by insiders but also have attractive valuations. The last quarter saw substantial insider selling of Nasdaq shares. In total, President Tal Cohen dumped US$750k worth of shares in that time, and we didn't record any purchases whatsoever. This may suggest that some insiders think that the shares are not cheap. Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. We usually like to see fairly high levels of insider ownership. It's great to see that Nasdaq insiders own 0.6% of the company, worth about US$268m. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders. An insider hasn't bought Nasdaq stock in the last three months, but there was some selling. Despite some insider buying, the longer term picture doesn't make us feel much more positive. On the plus side, Nasdaq makes money, and is growing profits. It is good to see high insider ownership, but the insider selling leaves us cautious. While it's good to be aware of what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision. In terms of investment risks, we've identified 1 warning sign with Nasdaq and understanding this should be part of your investment process.
