A Brief History of the Universe
By Sarah Alam Malik, Published by Simon & Schuster (UK, February 12) and William Morrow (USA, May 5)

Published in 1988, Stephen Hawking’s A Brief History of Time revolutionized the field of cosmology and became a bestseller. As a curious teenager, I attempted to read it, but I never finished. Now, nearly four decades later, particle physicist Sara Alam Malik offers her own perspective on cosmology with A Brief History of the Universe (and Our Place in It).

While Hawking’s work began with Aristotle’s heliocentric theory from 340 BC, Malik traces our understanding back to Babylonian astronomical observations recorded in cuneiform around the 7th century BC. The journey then progresses through the contributions of Aristotle and Ptolemy, reaching the flourishing of astronomical sciences in the Islamic Golden Age during the 6th century AD.

This concise history propels readers through significant milestones by page 47, covering Galileo’s discovery of Jupiter’s moons, Newton’s apple, and Einstein’s general relativity, ultimately exploring the mysteries of galaxies and black holes, leading to the concept of the universe’s thermal death. Malik adeptly connects cosmic-scale truths with the intricate world of quantum mechanics, stating, “The building blocks of the universe turned out to be as amazing as the structure of the universe they created.”

Unlike Hawking’s technical depth, Malik adopts a broader perspective, bringing to life characters such as Dmitri Mendeleev, who created the periodic table, and Fritz Zwicky, the pioneer of dark matter. Her narrative highlights a diverse cast, including medieval Islamic astronomers and groundbreaking women like Vera Rubin, who overcame gender barriers to reshape our understanding of galaxies.

Written with a more contemporary tone, Malik discusses topics Hawking could not forecast in 1988, such as the Large Hadron Collider, revealing the emotional impact of scientific breakthroughs like the Higgs boson discovery through compelling anecdotes.

This book is not only a “brief history of the universe” but emphasizes “and our place in it.” It narrates humanity’s discovery of the cosmos, underscoring our journey enabled by the giants before us. It evokes awe and humility, reminding us, “It remains a wonder of human existence that we can understand worlds so far removed from our own.” Each era has crafted its narrative of the universe, often believing its own version.

At its best, Malik’s work dives deeply into cosmic and quantum mysteries, aligning with her expertise in dark matter. While chapters on the origin of life, its future, and machine intelligence may feel less thorough, her warm, clear prose covers an impressive breadth within just 223 pages. As an 18-year-old, I might have navigated this complex narrative and been inspired to follow in Hawking’s footsteps.

The incredible picture captures the closest Einstein ring ever seen

The closest Einstein ring ever picked up by the European Space Agency's Euclidean Space Telescope

Astronomers have identified the closest Einstein ring ever. This is a rare phenomenon in which light from even more off-the-sea galaxies bend due to the gravity of galaxies near Earth. The ring was previously thought to be one galaxy, and was identified over 100 years ago.

Such a galaxy lens, the closest astronomer to date, was predicted by Albert Einstein in 1936 from his general theory of relativity. At the time, he thought it was impossible to observe such an effect. In fact, if he had a strong enough telescope, he would have seen it. “It was there all along, but we didn't know.” Thomas Collett At the University of Portsmouth, UK.

Colette and his team are about 600 million light years from Earth, and the oval galaxy NGC 6505, first discovered in 1884, is actually the second galaxy behind about 600 million light years from Earth. I noticed that the light was bent.

Team Members Bruno Artieri We observed Einstein rings at the European Space Agency while verifying early test data from the Euclidean telescope. “There was this abundant and obvious Einstein ring. There aren't many in the universe that can produce rings like this,” says Colette.

“We would have expected about one of three opportunities to find something as spectacular as this throughout the research,” he says. “It's essentially a great fortune to find it in the first data. This is probably the most beautiful lens we find on a mission.”

The ring itself is very bright compared to most Einstein rings we know, Colette says. This is not only very close to us, but also due to the Euclidean imaging capabilities. “I'm like someone with poor eyesight,” says Colette. This makes it easy to see four images of distant galaxies. The faint orange lights surrounding the bright ring are the galaxy of Rensing.

Bringing the Einstein ring closer to Earth allows us to test relativity in ways that we cannot do with other distant lenses, says Colette. This is because galaxies can be measured in two ways. , often too far to measure accurately. Einstein's general theory of relativity states that these masses should be the same, so if there are differences it may suggest that the theory of gravity should be revised.

When Colette and his colleagues measured the mass of the lensed galaxy, they also found a slightly higher number than possible from the galaxy's estimated number of stars. This could be due to the dark matter aggregation together at Galaxy's Center. Frédéric Dux He says observatory in southern Europe needs to find more Einstein lenses to check.

Are you an insect fan? Please leave now: Victory image Royal Insect SocietyThe 2024 photography competition has been announced.

This year's close-up creature selection has a very terrible appearance beetle, unfortunate mummy hornet, and a unique monochrome butterfly. However, according to the judge, the most interesting picture was a photo of Gnart's egg (not Srek's parent Relative, but a robbery). This image, snapped by Benjamin Salb, is introduced in incredible details of the crimson eyes of the bug wide set.

The overall winner of the “Under 18” category was Alexis Tinker Zabara, a 17-year-old German photographer, and was an image of a big woman's jagged bug waiting for her prey on the flower head.

The Royal Insect Society exists to enhance the general understanding and gratitude of insects and the diverse and important roles they play in our global ecosystem.

Hannah Fry reveals how technology can empower us in health, but cautions that data alone is not the full picture | Unlocking Hannah Fry’s Formula for Life

Throughout history, there have been many individuals who meticulously monitored their weight, but one of the most intriguing figures is Santorio Santorio. In the 1500s, he devoted his life to tracking his body, weighing everything he consumed and everything he excreted.

For a particular scientific investigation, he created what he called a sanctorian weighing chair – a chair placed next to the dining table on a steel scale that closely monitored one’s weight.

His theory was based on the idea that individuals could maintain their weight by consuming the same amount that their bodies expelled (urine, feces, sweat, or what he referred to as “insensible sweat”). If it detected overeating, the chair would lower, making it impossible to reach the food. This would prevent further consumption until the end of the meal.

Despite being mocked at the time, Santorio’s concept had merit. The notion of a personalized, experimental, and quantitative approach to health is undeniably appealing.

Nearly two centuries later, Benjamin Franklin, inspired by Santorio, meticulously recorded his dietary intake and compiled a list of all 13 of his virtues. He marked them whenever he committed an immoral act, monitoring and quantifying his life in great detail.

In the modern era, individuals have pushed boundaries with technology to track various aspects of their lives. For instance, a Reddit user created a beautiful visualization depicting a baby’s sleep and wake times during the initial months of life.

The advancement of wearables has made monitoring our health easier than ever. With technology, we can now effortlessly track various health metrics. AI-powered wearables connected to smartphone apps can monitor sleep patterns, blood oxygen levels, heart rate, and blood pressure.

Having access to objective numbers and data can be reassuring. It can serve as a motivator for achieving our health goals and connecting with communities that prioritize health tracking and accountability. However, it’s essential not to prioritize tracking numbers over happiness and well-being.

When it comes to fitness, remember that numbers are merely proxies for what truly matters. Each individual is unique, and responses to external stimuli vary. While trackers can provide insights into what is “normal” for a person, this data should be used to inform rather than dictate health status. Human bodies are complex and should not be reduced to mere data points.
