    ✧ J. Robert Oppenheimer ✧

    J. Robert Oppenheimer (April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II. He is often called the "father of the atomic bomb" for his role in overseeing the development of the first...

  2. Quote from the podcast:

    "Back in 1945, there was this incredibly brilliant mathematician, John von Neumann and he was staring down the reality of the atomic bomb, the one he was actively helping to build.

    He basically said, "What we are creating right now is a monster, a monster whose influence is going to change history,
    *provided there is any history left.*"

    First: The "Blueprint." 🗺️
    Soviet intelligence (the NKVD) pulled off the ultimate heist by infiltrating the Manhattan Project. Spies like Klaus Fuchs didn't just send "tips"—they sent the full technical specifications for the "Fat Man" plutonium bomb. They didn't have to wonder if it worked; they knew it did.

  5. Officials order demolition of #US homes after discovering #radioactive hazard: 'Safety is our number one priority'

    "We've collected over 41,000 samples."

    by Brianne Nemiroff, March 7, 2026

    Excerpt: "The U.S. Army Corps of Engineers tested soil in the backyards of properties along the 800 block of Cades Cove Drive in #Florissant, #Missouri. It found #NuclearContamination between 2.5 and 17 feet below the foundations of the homes.

    "The homes were built near #ColdwaterCreek, a waterway that has experienced contamination issues since the 1940s. Now, in February 2026, six of the homes on this block will be demolished.

    "Lt. Col. Andrew James, Deputy Commander for the St. Louis District for the Army Corps of Engineers, said to Spectrum News, 'We've collected over 41,000 samples along Coldwater Creek. And although there's still more spots of contamination that we have to get, the data shows that these are the only homes that we have to demolish right now. For the residents in this area, especially the neighbors that are close … safety is our number one priority.'

    "Spectrum News also spoke to Gina McNabb, a resident of the block whose home of 28 years was demolished. 'My husband's had #cancer, my kids had illnesses, and that's not to say that it definitely came from this, but now there's a question.'

    "Federal authorities have not released the payouts to the affected homeowners; however, McNabb has confirmed that her home loan and moving expenses were paid off.

    Those who participated in the #ManhattanProject focused more on physics than on the biological effects of radiation. Eighty years later, experts are still finding radiation in the soil under homes, in waterways, and an increased cancer risk in people living near high-risk areas, as stated by experts in an interview with PBS."

  12. After Russia in December, the USA also published news about a nuclear reactor on the Moon yesterday. I wonder, why the Manhatten Project is mentioned in that context.

    “History shows that when American science and innovation come together, from the Manhattan Project to the Apollo Mission, our nation leads the world to reach new frontiers once thought impossible,” said U.S. Secretary of Energy Chris Wright.

    The 80th anniversary last week of the atomic bombings that helped end World War II came at a most peculiar time. That is in part because we can’t mark that anniversary without also noting the astonishing Manhattan Project that built atomic weapons.

    The Manhattan Project was a towering achievement, one of the great stories of human effort and accomplishment. Yet the Trump administration has been systematically dismantling the culture of research that the Manhattan Project and World War II bequeathed us, a culture that propelled American prosperity.

    At no other time in modern history has a country so thoroughly turned its back on its core national strengths. The very elements that made the Manhattan Project such a success are today under assault. With devastating cuts to science and health research, the administration is turning its back on a history of being powered and renewed by the innovation and vision of immigrants. What America may find is that we have squandered the greatest gift of the Manhattan Project — which, in the end, wasn’t the bomb but a new way of looking at how science and government can work together.

    That the Manhattan Project happened is itself a minor miracle. For nearly two years, the U.S. military seemed to want nothing to do with the effort of inventing an atomic bomb.

    From 1939 to 1941, a ragtag group of mostly Jewish refugee scientists from Hitler’s Europe, including Albert Einstein, approached the government and met with military officials. The scientists educated them on the discovery of nuclear fission, its implications for war and their fears that Hitler would develop an atomic bomb first.

    The military brushed them off. “The colonels kept rather aloof,” the physicist Eugene Wigner recalled after one such meeting in October 1939, as Hitler took Poland. “They were friendly, they smiled, but they never expected to see a working atomic bomb in this world.”

    One of those colonels told Wigner and Edward Teller, dismissively, that he would award $10,000 to whoever could develop a death ray and prove it by killing a goat — the implication being he imagined that project more likely than a bomb that unlocked the power of the fundamental building block of the universe.

  18. OpenAI CEO Sam Altman has expressed deep unease about the capabilities of GPT-5 AI model expected to launch in August 2025.
    Altman said testing the new model left him feeling "useless" and likened its development to the Manhattan Project, that produced the first atomic bomb.
    He is concerned that AI is advancing too quickly for regulators and society to manage. As GPT-5 nears release, even its creators are sounding the alarm.

  20. #Navajo #uranium miners, people #downwind of atom bomb tests demand justice as Congress lets aid program lapse

    by Keetra Bippus / Cronkite News
    July 5, 2024

    WASHINGTON – "A federal program to compensate people exposed to fallout from U.S. nuclear testing expired June 10.

    "The #Radiation Exposure Compensation Act has paid out $2.6 billion to over 41,000 people since 1992. In March, the U.S. Justice Department projected that another 1,070 claims would be approved by the end of September.

    “'Why do we have to beg to pass #RECA?' said #MaggieBilliman, whose father, a #NavajoCodeTalker during World War II, died of stomach cancer she attributes to exposure to #fallout that affected their hometown in #Arizona. 'You don’t put a price tag on human life.'

    "Starting with the #ManhattanProject’s Trinity test on July 16, 1945, weeks before bombs destroyed #Hiroshima and #Nagasaki, the U.S. government conducted 94 tests that produced radioactive mushroom clouds in remote areas of the West. Most were over #Nevada. One was over #NewMexico.

    "People #downwind – including many in #Arizona – were exposed to dangerous #fallout, typically without warning.

    "The Billimans’ hometown, #SawmillArizona, on #NavajoLand, is part of the large affected area where Congress made residents eligible for compensation.

    "#Radioactive particles fell throughout Arizona, according to research from Princeton University’s Program on Science and Global Security. The state’s population grew from about half a million just before World War II to over 1.3 million in the early 1960s.

    "Congress adopted RECA in 1992 to address claims from downwinders and uranium miners.

    "The program offers an apology, and lump sum compensation ranging from $50,000 to $100,000 to those who developed certain illnesses linked with radiation exposure, and who either lived in the #FalloutZones or worked at #UraniumMines and #UraniumMills.

    "The law came in response to lawsuits from uranium workers who accused the government of failing to warn them about radiation hazards.

    From 1944 to 1986, nearly 30 million tons of uranium ore was extracted from Navajo lands. The Manhattan Project itself, led by physicist #RobertOppenheimer, was disbanded in 1947, two years after Japan surrendered to end World War II.

    "An estimated 3,000 to 5,000 Navajo people worked in the mines. They and their families lived nearby.

    “'The closer you live to mine waste, the higher your risk of chronic #metabolic disease,' said Chris Shuey, director of the Uranium Impact Assessment Program at the Southwest Research and Information Center, a nonprofit research and advocacy group. 'People who live in these communities next to these wastes, they’re exposed through all of the pathways: air, water, land.'

    "Claims from Arizona, New Mexico, Utah and #Colorado account for $1.8 billion of the payouts under RECA.

    "Most of the #NavajoNation was covered due to potential fallout. About one in seven approved claims – 5,480 through the end of 2023 – have come from #NativeAmericans, 86% of them Navajo, totalling $372.6 million.

    "The Environmental Protection Agency counts 523 abandoned uranium mines on or near the Navajo reservation that spans Arizona, New Mexico and Utah, an area bigger than Massachusetts, New Hampshire and Vermont combined.

    "The Senate voted 69-31 in March to extend the RECA filing period for five more years, with 46 Democrats and 20 Republicans in favor, along with Sen. #KrystenSinema of Arizona and two other independents. Sen. #MarkKelly, D-Ariz., also supported the bill.

    The bill has stalled in the House, with no explanation from Speaker Mike Johnson or Majority Leader Steve Scalise, both Republicans from Louisiana.

    "Their aides did not respond to multiple requests for comment."
