    When a car accelerates, brakes, or turns, physics explains what is happening. Newton’s laws help us understand how forces affect objects and why seat belts are so important for safety. 🛞

    **Electricity and Energy:**
    Every time we switch on a light, charge a device, or use a household appliance, we are using electrical energy. Physics helps us understand how electricity travels and how it can be transformed into useful forms of energy.

    **Light and Vision:**
    The colors we see, reflections in mirrors, shadows, lenses, cameras, and even rainbows can all be explained through the behavior of light.

    **Sound and Communication:**
    When we speak, listen to music, or make a phone call, sound waves and vibrations are involved. Physics explains how these waves travel and how technology allows us to communicate across enormous distances.

    **Heat and Temperature:**
    Why does ice melt? Why does hot tea cool down? Why do refrigerators keep food cold? Physics helps explain the movement and transfer of thermal energy.

    **Gravity and Our Planet:**
    Gravity keeps us on the ground, holds the Moon in orbit, and helps keep planets moving through space. Without gravity, our world would be completely different!

    **Physics and Modern Technology:**
    Modern technology depends heavily on physics. Smartphones, computers, satellites, medical equipment, cameras, transportation systems, and renewable-energy technologies all rely on scientific principles.

    Learning physics can change the way we look at the world. Instead of seeing ordinary events as simple or mysterious, we begin to recognize the fascinating science behind them. Every movement, sound, light source, electrical device, and changing temperature becomes an opportunity to ask questions and discover something new.

    **Physics encourages curiosity.**
    It teaches us to observe carefully, ask meaningful questions, test ideas, solve problems, and understand the evidence around us. It shows us that science is not just a school subject—it is a powerful way of understanding our world.

  • Today, I had an insightful 15-minute AI session where I delivered a talk assigned by our mentor, Doulat EducationWala Bhai, during the earning class. The topic was the rise and fall of BlackBerry—how it was once a top-tier brand in the market and eventually declined to a lower level.

    In this session, I discussed BlackBerry’s entire history, from its initial peak dominance in the smartphone industry to the reasons behind its downfall and why it is no longer visible in the market today.

    It was a great learning experience, and I’m grateful for this opportunity to analyze such a powerful case study.

    Biggest ironies in Pakistan

    1) Wed rather spend more on daughters wedding than on her education.

    2) We live in a country where seeing a policeman makes us nervous rather than feeling safe

    3) Pakistanis are very shy and still are 18 Crore.

    5) Pakistanis are obsessed with screen guards on their smartphones even though most come with scratch proof Gorilla Glass but never bother wearing a helmet while riding their bikes.

    6) Politicians Divide us, Terrorists Unite us

    7) Everyone is in a hurry, but no one reaches on time

    8) Its dangerous to talk to strangers, but its perfectly ok to marry one

    9)The shoes we wear are sold in air Conditioned showrooms, the things we eat are sold in open....!!!

  • Last week, a Redditor named easyjet decided to (very belatedly) join the global party that is Facebook. He signed up with an email address he never, ever used. He lied about all of his personal information.

    So he was rightly freaked out when Facebook still managed to predict and "recommend" a huge number of his real-life acquaintances - down to people whose names he barely knew and a woman he dated 19 years ago.

    How does Facebook know who your friends are? Its a mystery that has nagged users since at least 2011, when the Irish Data Protection Commissioner conducted a full-scale investigation into the issue. But four years later, theres still a lot of confusion and misinformation about what Facebooks doing when it "finds" your friends.

    Did it scrape your phone for names and numbers? Run a reverse-image search of your picture? Compile a "shadow" or "ghost" profile on you over a period of years, just waiting for you to log on and "confirm" its guesses?

    Alas, Facebooks actual process isnt actually that sneaky or malicious. In fact, it involves this pretty complex academic field called ... network science.

    In a nutshell, whenever you sign up for a Facebook account, Facebook asks permission to look at your email contacts if youre on a computer, or your phone contacts if youre on a smartphone. When you grant the site permission, it searches your contacts for users already on the network, and it searches other users uploaded contacts for you. That gives it a very primitive outline of your social circles: who you know, but not how you know them or how well.

    To refine that map, Facebook asks you more questions about yourself: where you went to school, when you were born, what city you live in. Each field in your Facebook profile and each interaction you make through that profile actually double as a source of data for Facebooks mapping algorithms. What theyre trying to do is determine the structure of the network: where the cliques are, which people bridge them, who knows who.

    Once Facebook knows the structure of your social network, it can analyse it to predict (with startling accuracy!) not only the people youre most likely to know now, but the people youre most likely to know in the future.

    This isnt magic: Its actually closer to statistics. In the network, there are a set number of "nodes," i.e., people, and a set number of "edges," i.e., friendships. Given that, each nonexistent connection between two nodes is a statistical possibility. But not all nodes are created equal, so not all connections are equally likely. (I dont anticipate befriending many 40-year-old guys in Siberia, say.)

    To estimate which connections are most likely, Facebook can run analyses against the structure of the network, using a long and entirely above-our-pay-grade list of coefficients and indices. Those coefficients account for a huge number of things: How many unusual commonalities do two people share, for instance? How many friends do they have in common? Which people in the network serve as rallying points, the people who know everyone? How many "degrees of separation" exist between them, how many friends of friends?

    In the end, Facebooks friend-recommendation system isnt magic or malice - just really good math. And guessing your future friends isnt telling the future; its modelling the evolution of Facebooks social graph.

    As you and I know, of course, this doesnt always work. Facebook, not infrequently, suggests you "may know" somebody that you dont. Or it suggests people you do know but dont want to see in your News Feed. Thats not Facebooks fault, says David Liben-Nowell, a computer scientist at Carleton College who studies the evolution of social networks.

    There are some forces outside the network that Facebook could never account for, he says: like what if I randomly sat next to a middle-aged Siberian man on a plane? And on top of that, Facebooks dealing with a vast and complex network.

    Liben-Nowell poses the example of your college roommates exes, some of whom you may want to Facebook-friend.

    "But which ones? And why?" He asks. "Their network positions relative to you are all pretty much the same, but you (only) know the one who you happened to sit beside at a wedding before your roommate dumped them. But Facebook doesnt know which college roommate was at Table 7 with you, so its prediction algorithms can only do so much."

    That said, both Facebook and mathematics at large have enormous interest in improving models of social-network change and "link prediction"; after all, the way people connect has implications way outside social networking, in fields as diverse as epidemiology, communications and counterterrorism.

    "We continuously update the People You May Know algorithm to make it better and more relevant for people," a Facebook spokesperson, Ana Brekalo, said.

    So in the future, Facebook may know even more about your friends.

And on top of that, Facebook's dealing with a vast and complex network. Liben-Nowell poses the example of your college roommate's exes, some of whom you may want to Facebook-friend. "But which ones? And why?" He asks. "Their network positions relative to you are all pretty much the same, but you (only) know the one who you happened to sit beside at a wedding before your roommate dumped them. But Facebook doesn't know which college roommate was at Table 7 with you, so its prediction algorithms can only do so much." That said, both Facebook and mathematics at large have enormous interest in improving models of social-network change and "link prediction"; after all, the way people connect has implications way outside social networking, in fields as diverse as epidemiology, communications and counterterrorism. "We continuously update the People You May Know algorithm to make it better and more relevant for people," a Facebook spokesperson, Ana Brekalo, said. So in the future, Facebook may know even more about your friends. By @Caitlin Dewey
