The Map of Physics

The Map of Physics

Physics is a huge, complex field. It also happens to be one of the most fascinating, dealing with everything from black holes and wormholes to quantum teleportation and gravitational waves.
But unless you have an innate knowledge of the field, it’s pretty hard to figure out how all these concepts actually fit together – and how they tie in with the stuff like the physics of inertia and circuits that we learnt in high school.
After all, everyone is constantly trying to prove Einstein wrong, and Stephen Hawking famously struggled to come up with a ‘theory of everything’, so it’s easy to get confused about how things do actually fit together in physics (if at all).
To straighten that out once and for all, YouTuber Dominic Walliman has created a map that shows how the many branches of physics link together, from the earliest days of classical physics and Isaac Newton, all the way through to Einstein’s relativity and quantum physics (with a little bit of philosophy thrown in there for good measure).
It takes you all the way from Newton’s falling apple to today’s scientists trying to peer inside black holes and find a theory to unify gravity with quantum mechanics.
The video shows that there’s a gaping “chasm of ignorance” that physicists need to fill in before we can truly understand how the Universe works. This includes things like dark matter and energy, which work in theory, but so far have never been directly observed or explained.
The bottom line in all of this is that, the more we learn, the more we realise how much we have left to discover, and that’s one of the things we love the most about science.
So, for anyone who’s ever hurt their brain by trying to think about what the Universe is expanding into, or what exactly space-time is made of, this is for you. Because when the history of physics is broken down into a palatable 8 minutes, it suddenly doesn’t seem so scary after all.

Indian Forest Expanded by in Last 2 years

Environmental Protection, Nature Conservation, Ecology
The forest and tree cover in India risen by 5,188 square kilometers in the last two years. Karnataka is growing the maximum protection of 1,025 sq km. There is an increase of 3,976 sq. Km (0.56 percent) of forest cover and 1,212 sq. Km (1.29 percent) of tree cover compared to the 2017 report.
Different States – Forest 
The three states in terms of forest cover are KarnatakaAndhra Pradesh, and KeralaKarnataka grew the maximum forest-and-tree protection at 1,025 sq km, Andhra Pradesh grew a 990-sq. Km cover and an 823-sq.km of forest cover created by Kerala in the last two years. Two other states followed are Jammu and Kashmir, which grew a 371-sq. Km forest cover, and Himachal Pradesh. The current assessment shows an increase of 544 sq. Km (0.19 percent) in 140 hill districts of the country. The forest data of Jammu and Kashmir, recorded through satellite imaging, covers areas outside LoC that are under the illegal occupation of Pakistan and China. The north-east did not show positive results as the current assessment showed a decrease of forest cover to the extent of 765 sq. Km (0.45 percent) in the region. The total forest cover of India is 7,12,249 sq. Km is 21.67 percent of the geographical area of the country. The tree cover of the country is estimated at 95,027 sq. Km, which is 2.89 percent of the geographic area. India on track to achieve its climate goal of creating an additional carbon sink of 2.5-3 billion tonnes under the Paris Agreement.

World Biggest Air Purifier

An experimental tower over 100 metres (328 feet) high in northern China – dubbed the world’s biggest air purifier by its operators – has brought a noticeable improvement in air quality, according to the scientist leading the project, as authorities seek ways to tackle the nation’s chronic smog problem.
The tower has been built in Xian in Shaanxi province and is undergoing testing by researchers at the Institute of Earth Environment at the Chinese Academy of Sciences.
The head of the research, Cao Junji, said improvements in air quality had been observed over an area of 10 square kilometres (3.86 square miles) in the city over the past few months and the tower has managed to produce more than 10 million cubic metres (353 million cubic feet) of clean air a day since its launch. Cao added that on severely polluted days the tower was able to reduce smog close to moderate levels.
