    It's funny to hear, 30 years after this lecture the concern for the holes that used to be in the ozone. Back then it was absolutely a serious issue, lol, now in 2024 the holes have nearly entirely disappeared. I bet climate change and pronouns will go the same route. In 20/30 years climate change and gender dysphoria will be an embarrassing memory that everyone will avoid talking about

    Carl Sagan explains the many observations made with Discovery 1 and Discovery 2. The picture of the pale blue dot was taken by Discovery 1 . Today NASA managed to recuperate signals from Discovery 1 - 46 years after its launch - as it leaves the solar system and ventures further- far overreaching its goals. The James Webb telescope gives us startling pictures of galaxies that we could only imagine when Carl Sagan made this speech. But his message then is further proven correct by scientific evidence. We miss Carl Sagan today to give us a glimpse of this

    He was living in my hostel during his iit tenure, once we happen to work on something as an assignment in engg physics course I guess so I went to his room, was surprised to see he keeps footwear outside the room and asked me to do the same. Very neat and clean this guy likes to live (those who lived in iitd hostels would know what I am talking about😅) Great guy, loves to argue logically, he does not utter a single word which somehow won't connect with what's going on in the conversation. Good to see him following his passion, i have seen few AIR 1s before, but this one is different

    In a world where lies are the currency; telling the truth is a revolutionary act. The western messaging, western media, it’s all NOT ONLY UNTRUE, it’s like the complete inversion of the truth-I call it “anti truth.” These anti truths are ubiquitous and the only way you can make sense of what we are seeing predominant in every western country is to hypothesize that those with power are PURPOSEFULLY toppling our societies. Thereafter you may host all sorts of plausible ideas as to motives

    As sunlight warms the surface of the Earth, heat radiates away from our planet as infrared radiation which passes freely past the atmospheric gases of nitrogen and oxygen. Indeed, if it weren’t for greenhouse gases such as carbon dioxide that do interact with and impede the escape of Earth’s radiant heat, the planet would be frozen solid. Thankfully, even though greenhouse gases comprise only 4/10ths of one percent of the atmosphere, they are powerful enough to maintain this ‘blanketing effect’ by constantly absorbing and releasing the infrared photons over and over, again and again. In doing so, they vibrate wildly, thus causing them to vigorously collide with other atmospheric molecules. This imparts the kinetic energy of motion throughout the atmosphere and registers as temperature. For more, search: ‘Enhanced Greenhouse Effect’; then ‘Amplified Greenhouse Effect’. For the big picture, search: Marcott reconstruction chart

    Some are meant to be read and not to be suddenly put under a spotlight. Ai, at every driveway, is already too far into the writer or theorist who retreats to isolation to work or study. That is the tripping point here. The phone is a stage in hand and the performer wasn't prepared for the part. A dark place behind the stage is the right place to point to the door or, some will bristle and shoot poison arrow hairs at what they sense is an odd intruder.
