"In pelicans flying in a V-formation, a heart rate 11% lower was observed compared to a solitary flying pelican. "

"So when an egg is cooked for too long or at too high a temperature, sulfur from the proteins, and it is rich in sulfur-containing amino acids, which is why it smells of hydrogen sulfide when it spoils. So the sulfur from the amino acids combines with the iron found in the yolk, forming iron sulfide. Iron sulfide, which is grayish-dark green and generally harmless to health in the quantities in which it is formed. "

"Eggs are super strong. Last updated: 23.04.2011 00:02. It's incredible, but just 3 raw chicken eggs can support the weight of an adult human. Due to its shape and purpose, which is to protect the embryo, an egg is an extremely durable structure – remind physicists from the University of Silesia in Katowice. An egg shell is a composite material, but primarily calcium carbonate, "nature's ceramic."1 We assume the ultimate compressional strength of the material to be about the same as bone (which is mostly calcium phosphate, but never mind): 170x106 N/m2. This egg shell constitutes of 95% of calcium carbonate which is the strength giving material, with some number of organic proteins and moisture content. "

"Research shows that a temperature above 15 degrees Celsius causes Salmonella enteritis bacteria to be detectable inside the egg as early as three days after laying, while at 10 degrees Celsius this process takes about 15 days. "

"This three-meter-tall 'Nielud' living in Madagascar laid eggs weighing, mind you, 10 kg. Several times heavier than today's ostrich eggs, over 150 times heavier than chicken eggs. These eggs were even 30-35 cm long. "

"However, if we consider the creature's mass in the size of the egg, the record goes to the hands, or rather wings, or perhaps even the beak, of the kiwi. This bird, weighing about 3 kg, lays eggs whose mass exceeds 400 g. Smaller females can lay eggs that constitute 15-20% of their weight. "

"In short, the color of the shell is the result of dyes, pigments deposited in it. White eggs, lack of pigments, then we have the default color of calcium carbonate. Such brownish, creamy colors are due to protoporphyrin. Green and blue are Biliverdin and its coordination compounds, most often with zinc. "

"Storing eggs at a temperature of a few, low dozen degrees Celsius is definitely recommended. Low temperature does not promote bacterial growth, reduces water loss through the shell, and increases protein stability. "

"If the water used for washing is colder than the egg itself, what's inside starts to decrease its volume. This is how cold works. Things shrink. As a result, we can say, negative pressure is created, which can actively draw potentially contaminated water along with bacteria through the pores I mentioned directly into the egg's contents. "

"Each lead brick weighs 25 lbs and one egg supported 10 bricks! "

"If by some miracle I found myself inside a professional peloton, shielded by an even larger mass of people, I could save 50% of power, even potentially more, because here we are constantly talking about 30 km/h, and these savings would proportionally be greater at higher speeds. "

"If I had someone riding at the same speed one meter in front of me, breaking the air for me, I would only have to generate 152 W, almost exactly 25% less. Let's add a second helper and my effort would be even less, 144 W. With a third, it would drop to 140 W, and with four helpers, it would be just 137 W. "

"The gain might seem small, around 5-7%, but it translates to a dozen-plus % lower induced drag, and theoretically, the improvement in the lift-to-drag ratio can be up to 30%. "

"Optimistic calculations suggest that thanks to this, flocks can cover greater distances, and that the range of such a migrating flock in a V-formation can increase by up to 70% in a single migration stage compared to a bird traveling solo. "

"To ride on a perfectly flat surface, without wind, without shaving my calves, at my mass, I currently need to generate 80-90 W if I want to travel at 20 km/h. To accelerate to 40 km/h, I would already have to generate over 380 W. "

"Uh, and this is quite important, because at the same time we know that this addition of iron makes the teeth of, among others, beavers much harder and more resistant to acids. "

"Duck eggs are better for baking, or at least for some baked goods. This is because proportionally they have a larger yolk, which can give baked goods more flavor and creaminess. Additionally, the yolk contains surfactants that promote emulsification, leavening, and foaming, which also benefits some baked goods. "

"A sudden change in temperature, for example, taking an egg from the refrigerator to a warm room, causes water vapor to condense on the shell. This moisture, combined with the temperature difference between the inside and outside of the egg, creates good, some even say ideal, conditions for bacteria to overcome the shell barrier. "

"Additionally, it should be remembered that in egg white we will find a substance with antibacterial properties, so the fact that a bacterium penetrates inside does not mean that it will spread there. The pH of the egg white itself is distinctly alkaline, around nine, which makes it difficult for microbes to survive. "

"Today, the Ostrich lays the largest eggs. The eggs of this 100-150 kg flightless bird can weigh up to 1.5 kg. That's equivalent to 20-30 chicken eggs. "

"Birds, which are technically also dinosaurs, I invariably emphasize this. And that is why they hold the record for the size of laid eggs. Today ostriches, and historically it was an extinct 'mamutak' from some 500-700 years ago, or rather an exterminated 'mamutak' from 500-700 years ago. "

"And when it comes to a record-breakingly large chicken egg, if I may rhyme, we are talking about 1956 and 454 g, which is 8 times heavier than standard. Maybe even 10 times, a huge egg. "

"Amniotic eggs, such as those laid by land animals, appeared around 310-340 million years ago, which is a much longer history than that of domestic chickens, whose origins are dated to thousands of years ago. "

"Chickens produce the protein ovocleidin 17, which is essential for creating the eggshell. And this protein is produced not by the egg, but by the animal, which is obvious. So there would be no egg without the skin. However, this is not something unique to chickens. Other birds, turkeys, finches have analogs of this protein. "

"If we consider an egg to be a biological structure from which some creature hatched, then the egg is obviously older. We know that animals laid eggs as early as 500-550 million years ago in the early Cambrian period. "

"In a chicken egg, we have further barriers in the form of two membranes with a total thickness of about 80 micrometers. They act as bacterial filters. The inner membrane is particularly effective here, which, thanks to a denser network of fibers, better stops microorganisms than the outer membrane. "

"In smaller formations with smaller birds, their wake structure might not persist, it might decay. "

"If you look at pictures of a beaver, you will see that its teeth are very red, very orange, and for a very, very long time it seemed logical. Because we have long known that the enamel of these rodents is rich in an element called iron. "
