For centuries, sailors told of giant waves rising from calm seas. Scientists dismissed them as myths. Then, on Jan. 1, 1995, instruments on an oil rig logged an 84-foot wave. Rogue waves were real, just rare enough to escape proof. This week, we got a rogue wave. After the midterms, Wednesday brought 342 unusual inflows,… Read more »
The Great Swap In February 1995, Newsweek ran a column by astronomer Clifford Stoll called, “Why the Web Won’t Be Nirvana.” He mocked the idea of shopping online. Over 30 years later, the company that started selling books online just reported $202 billion in quarterly sales. Its stock fell anyway. Doubting the future is popular,… Read more »
Trees don’t lose their leaves in the fall. They cut them off. Before a leaf drops, the tree pulls back about half of its nitrogen and stores it for spring. Then it grows a thin layer of cells at the base of the stem and seals the leaf away. What looks like dying is really… Read more »
Frozen, Not Dead Each fall in Alaska, the wood frog lets itself freeze. Up to 60% of its body turns to ice and its heart stops. Pretty much dead, it can stay that way for seven months. But first it goes through 10 to 15 freeze-and-thaw cycles. Each one builds up glucose that works like… Read more »
Near Manaus, Brazil, two giant rivers meet but don’t mix. The Rio Negro is dark as coffee, warm, and slow. The Solimões River is sandy, cool, and moves two or three times faster. For about four miles, they flow side by side in the same channel, one black and one tan, with a line between… Read more »
When the days get longer, the cold gets stronger. The shortest day of the year is Dec. 21, but it’s not the coldest – not even close. East of the Rockies, the coldest stretch usually shows up about a month later. Land, air, and water hold on to heat, so it takes weeks for the… Read more »
There Are Indexes and There Are Markets Some of the biggest waves on Earth never reach the surface. In the Luzon Strait, between Taiwan and the Philippines, tides push cold, heavy water over two seafloor ridges. That sets off waves deep inside the ocean that can grow 550 feet tall. That’s higher than the Washington… Read more »
When light is low, our eyes shift from cones to rods. Known as the Purkinje effect, cones handle color in bright conditions while rods take over when light fades. Vivid reds nearly disappear. Blues and greens become more visible. Your eyes are working fine, the light conditions simply changed. What you see depends on how… Read more »
The world changed on Sept. 11, 2001. For those who were there, and for those who lost someone who was, I take a moment to remember them. History lives through memory…never forget. In 1962, U.S. Naval researchers discovered something remarkable. When a nickel-titanium alloy called Nitinol bent out of shape and then heated, it snapped… Read more »
The Lever Archimedes said, “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” He was describing physics. He was also accidentally describing the political calculus of September 2026. Oil is the lever. The Strait of Hormuz is the fulcrum. And the same mechanism creating… Read more »
