Did you know that there’s a book no one will ever be able to finish reading in their lifetime, and it only has 10 pages?
In 1960, the French writer Raymond Queneau introduced what is probably the world’s longest book. It’s called *Cent mille milliards de poèmes* (A Hundred Thousand Billion Poems), and it consists of just ten pages, each containing a sonnet. The verses all share the same rhyme pattern and are printed on strips, allowing readers to combine lines from different sonnets.
This setup results in a total of 10¹⁴ possible combinations, meaning the book contains one hundred trillion unique poems. The implication is that no one will ever manage to read the entire book, even with the greatest effort, as it would take millions of years to match up all the possible poem combinations—without taking breaks for eating, sleeping, or reading anything else. And all of this comes from just ten pages!
Each mix you create will result in a coherent sonnet with proper stanzas, rhythm, and rhyme. Moreover, it’s highly likely that any randomly selected poem will be one that no one has ever read before. Queneau himself claimed that if it takes about 45 seconds to read one sonnet and another 15 seconds to prepare the next, it would take around 200 million years to read through all the possible combinations.

What's the difference between X-Ray, CT scan, and MRI?
X-rays use electromagnetic radiation to create images of bones and dense structures within the body. It is commonly used to detect fractures, infections, tumors, and other abnormalities.
X-rays are quick, relatively inexpensive, and readily available.
CT scans use X-rays and advanced computer processing to create cross-sectional images of the body. They provide more detailed information than traditional X-rays and can show bones, organs, blood vessels, and soft tissues.
CT scans are useful in diagnosing conditions such as internal injuries, tumors, infections, and blood clots.
MRI uses a strong magnetic field and radio waves to create detailed images of soft tissues, organs, and structures inside the body. It provides excellent contrast between different types of soft tissues and is particularly useful for imaging the brain, spinal cord, joints, and muscles.
MRI does not involve ionizing radiation, making it a safer option for imaging, especially for pregnant women and children.
However, MRI scans take longer to perform, are more expensive, and may not be suitable for individuals with certain medical implants or metal objects in their bodies

Cave di Cusa was an ancient stone quarry in Sicily, renowned as the primary source of stone for the construction of the temples in the ancient Greek city of Selinunte. Quarrying began in the 6th century BC and abruptly ended in 409 BC when Selinunte was sacked by the Carthaginians.
The site is famous for its massive, unfinished columns, some still attached to the bedrock, frozen in various stages of production. The precision of the quarrying techniques used to extract and shape these enormous stones remains a topic of debate, showcasing the ingenuity of ancient Greek engineering.

💚 Father's Pride: How Many Babies Can You Count? 🐊
This incredible image by Dhritiman Mukherjee captures a father gharial crocodile in India's National Chambal Sanctuary with his many offspring clinging to his back.
The photo was highly commended in the Wildlife Photographer of the Year competition.
Sadly, the gharial is critically endangered, with fewer than 1,000 mature individuals remaining in the wild. This photo is a heartwarming reminder of the importance of conservation efforts.

“When you see someone sitting on the floor with their dog on them in public (like in this photo), they aren't just "cuddling" their dog. The dog is actually actively performing a task called deep pressure therapy.
9 out of 10 times if you see someone like this, they are experiencing some kind of medical episode. This is not the time to ask them questions, ask/attempt to pet their dog etc. At most, ask if the handler is OK and needs anything but nothing more.
This task can help with many different medical issues but for me when Levi does this, he is helping lower my heart rate and thus helping to prevent a fainting episode!
Service dogs are so amazing. They have such big jobs which is why it's so important to never distract them.”

Scientists Made an Ultra-Thin Material That Stops Bullets by Hardening Like a Diamond
Researchers from The City University of New York (CUNY) have discovered a groundbreaking new material called diamene, which has the potential to revolutionize bullet-proof armor.
Diamene is created by stacking two layers of graphene, a one-atom-thick sheet of carbon atoms arranged in a honeycomb pattern. While graphene is already known as the world’s strongest material, this new configuration gives it a remarkable property: under sudden mechanical pressure, diamene temporarily hardens to a diamond-like consistency.
Unlike traditional bullet-proof armor, which is often heavy, diamene-based materials could offer the same level of protection without the added weight.
