    1. What Is the Quadruple Star System? The system contains four celestial bodies grouped in two pairs. One pair is young red dwarf stars, common and relatively bright. The other pair consists of cold brown dwarfs, faint objects about the size of Jupiter. The brown dwarfs orbit the red dwarfs in a hierarchical arrangement. This system is unique because brown dwarfs rarely have companions and are seldom found in multiple-star systems.

    4. Where once there were editors, publishers, and gatekeepers for the content we consume, now anyone with a smartphone can write, record, film, and publish with reckless abandon.The Internet has democratized the sharing and distribution of creative content. In the past, you needed talent and connections, now you just need a smartphone and social media accounts to share whatever you like.This is a good thing because it’s easier than ever to share content, and the underrepresented have a greater voice now. But it’s also a bad thing, for two reasons.First, our attention spans have diminished. Where once people could sit for hours immersed in a good book or an extended conversation, now they get restless if their favorite YouTube channel doesn’t load fast enough.Second, there is little to no quality control. Our lives are bombarded by millions of blogs, YouTube channels, and social media sites. Sometimes the cream rises to the top, but often the loudest, most outrageous, and superficial content gets all the attention.
      1. Democracy isn't always a good thing. For instance here, it has led to people being bombarded with low quality content.

      2. Now the onus of quality control is on the audience. They have to filter out the bad stuff.

The range is about 500 km (310 mi) in length and the most heavily glaciated part of the world outside of the polar regions. The Siachen Glacier at 76 km (47 mi) and the Biafo Glacier at 67 km (42 mi) rank as the world's second and third-longest glaciers outside the polar regions.[23] Just to the west of the northwest end of the Karakoram, lies the Hindu Raj range, beyond which is the Hindu Kush range. The southern boundary of the Karakoram is formed by the Gilgit, Indus and Shyok rivers, which separate the range from the northwestern end of the Himalayas.

    1. A katabatic wind (named from the Greek word κατάβασις katabasis, meaning "descending") is a drainage wind, a wind that carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds; the spelling catabatic winds[1] is also used. Katabatic winds can rush down elevated slopes at hurricane speeds, but most are not as intense as that, and many are 10 knots (18 km/h) or less. Not all downslope winds are katabatic. For instance, winds such as the föhn and chinook are rain shadow winds where air driven upslope on the windward side of a mountain range drops its moisture and descends leeward drier and warmer. Examples of true katabatic winds include the bora in the Adriatic, the Bohemian Wind or Böhmwind in the Ore Mountains, the Santa Ana in southern California, the piteraq winds of Greenland, and the oroshi in Japan. Another example is "the Barber", an enhanced katabatic wind that blows over the town of Greymouth in New Zealand when there is a southeast flow over the South Island. "The Barber" has a local reputation for its coldness.

    1. Improving nutrition calls for a systems approach, cutting across health, food and care systems with data-backed digital tools providing an enabling backbone to scale evidence-based interventions. There is growing evidence that convergent actions, especially agriculture-nutrition convergence and strengthening of demand-side behaviour can play a pivotal role in preventing undernutrition.

    1. Another suggested step is for blood banks across China to test blood samples from 2019 to see whether they carried antibodies for SARS-CoV-2. This could provide a clue to how early the virus was circulating in human populations.

      5

    2. One important step would be widespread sampling of animals in farms across China that supplied the markets in Wuhan in the search of ancestor viruses to SARS-CoV-2. Workers in farms need to be tested as well for exposure to SARS-CoV-2 or related viruses.

      4

    3. The only solution is to work with China

      3.

      getting China to cooperate is crucial for success in locating the origin of the virus.

      as this may requrire the suggested steps

    4. But science is being elbowed aside by politics

      2.

      politics over the origin of the virus is also complicating the task of researchers.

      some are blaming China . This can make the Chinese Govt uncooperative to the research. this would further complicate matters.

    5. finding virus samples from the earliest stages of the outbreak in Wuhan, reconstructing their genetic sequences, and then fitting them to a family tree that will hopefully lead to the common ancestor of the diverse strains and variants of SARS-CoV-2 that have spread globally. This could also provide clues as to whether this ancestor emerged in wildlife, in farms and markets, or from a laboratory.

      1.

      This is a challenging task. It requres painstaking collection so data and its analysis.

      other factors such as locating the patient zero also complicates this task.

      Strain A cases were never identified

      animal markets have been sanitized. animals sold in 2019 are not available for testing.

    1. I’m often surprised more people haven’t heard of a free wiki called TV Tropes. (It’s not just about TV). The site collects frequent tropes used in storytelling, explains how they work, and then lists endless examples in books, movies, and other media.

    3. You can even prime your mind to dream about specific problems. For example, if you mull over a problem right before drifting to sleep, chances are you will dream of working on it or even solving it.

      2a

    4. Sleep is probably the most effective way to swing the doors of lateral thinking wide open. While asleep, your brain is hard at work cementing what you’ve learned during waking hours

      2

    5. One of the best ways to get into lateral thinking is to go for a walk. Solitary walks ignite creativity, as testified by many inventive people throughout history.

    1. You’ll walk away from reading it with a better understanding of the theoretical concepts behind information and what it means to encode and decode information, what it means to process information, and how we measure the amount of information and how much information can be sent over our internet connections.

      3b

    2. The book explores the history of information and information processing as well as look at how figures like Charles Babbage, Ada Byron, Samuel Morse and Alan Turing (this guy again!) made key contributions. Then, it looks at Claude Shannon who created information theory — and gave rise to the “bit” — the binary digit — we’re familiar with today.

    3. walks the reader through the inner workings of computers using many illustrations and helpful analogies. Petzold slowly builds up the groundwork understanding needed to understand how computers work.Slowly, piece by piece, the book builds up a fully working computer including memory and screen.

      2a

    4. In the book, author Charles Petzold interleaves a biography of Alan Turing with his seminal work on computability, in many ways the genesis of our modern computer age. As the biography progresses, Perzold introduces the mathematical concepts needed to later explain Turing’s historic 1936 paper “On Computable Numbers”. It makes for fascinating reading, with Petzold’s annotations of Turing’s academic paper making it much more accessible.

    1. Perfection is a moving target. It's always moving away from us. It can never be reached.

      Chasing perfection is a waste of time, energy and resources.

      We never reach the end goal and we never deliver the results.

      This hurts our success and frustrates us and drains us .

      Doing work until is good enough allows us avoid the above scenario.

      We can deliver results and become successful.

      Consistency in doing something to be best of our ability is the key to success. Not trying to attain perfection.

    1. The point of a 5-hour workday isn’t to get everybody to work less. Instead, it’s to promote autonomy and stop productivity-shaming those who’ve found ways to produce the same value in fewer hours

      6

    2. When you find a way to work more efficiently and put in fewer hours, you’re penalized and thought of as lazy rather than celebrated for better results

      4.

    3. Research from Alex Pang, owner of Silicon Valley consultancy Strategy and Rest, and an author who has done extensive work on the ties between shorter working hours and productivity says, “5 hours is about the maximum that most of us can concentrate hard on something.”Henry Ford was way ahead of us. Henry messed with the idea of 5-hour workdays a long time ago and found they increased productivity.

      5.

    4. Productivity expert Cal Newport describes deep work as a “professional activity performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate.”

    3. Taking full responsibility for your learning is how you become a better version of yourself. To deliberately control your learning and unlearning process, find the top 1000 brilliant minds and consistently learn from them

      2

    4. I call it the 1000 minds rule because it’s the optimal number of people you can improve how you think. One thousand sources of knowledge is more than enough to learn new things every day.

    1. At any given point I have about 10-20 books on my “to go” list. Books that I can just pop in and continue reading. Every day I read at least 10% of a non-fiction book that gives me tons  of new ideas, an inspirational book, a fiction book of high-quality  writing, and maybe a book on games (lately I’ve been solving chess  puzzles). And then I start writing

    2. Bit if I’m coming up with business ideas, how do I know if I’m on the right track? There’s no way to know in advance if a business idea is a good one.

      3

    3. No idea is so big you can’t take the first step. If the first step seems to hard, make it simpler. And don’t worry again if the idea is bad. This is all practice.

      2

    4. I divide my paper into two columns. On one column is the list of ideas. On the other column is the list of  “FIRST STEPS”. Remember, only the first step. Because you have no idea where that first step will take you.

    3. In an article published in Inside Higher Ed in June 2020, Peter C. Herman, professor at San Diego State University, wrote of how his students responded when asked to narrate their experience of online education: “But for all their differences in age, gender, ethnicity, sexual orientation, citizenship and intellectual preparedness, they [i.e. students] universally agreed on their evaluation of online learning: they hated it.

    5. University Grants Commission’s latest proposal for “blended learning”, wherein up to 40 per cent of the courses a student takes up at the college/university level can be through the virtual digital mode, is in keeping with the vision of the NEP 2020, whereby physical campuses and classrooms are sought to be, wholly or largely, replaced by online entities.
