    Podcast Summary

    • Tides and PresenceUnderstanding tides' impact on human activities and their connection to the gravitational forces of the moon and sun can help us appreciate the importance of being present and adapt to life's ebbs and flows

      Being present, while desirable, isn't always easy and it's okay to acknowledge that. Comedians Bo and Yang discussed this on a recent episode of NPR's Wild Card podcast. Meanwhile, in history, the importance of being attuned to the environment was highlighted during the planning of the D-Day invasion in 1944. The tide range in Normandy was significantly larger than in most US locations, making precise timing crucial for the success of the operation. Tides can impact various human activities, from shipping and fishing to floods. Understanding their significance is essential. Now, let's shift gears and talk about tides on a grander scale. Imagine a massive water droplet the size of a planet. This droplet, as it interacts with the gravitational forces of the moon and the sun, creates the tides we observe. The next time you find yourself struggling to stay present or grappling with the complexities of nature, remember the tides - a constant, powerful force that ebbs and flows, much like our own lives.

    • Tidal patterns and natural disastersUnderstanding tidal patterns is crucial for predicting and preparing for natural disasters like flooding, with NOAA using tide charts and climate change data to predict flooding up to a year in advance.

      The earth's rotation and the gravitational pull of the moon and sun cause tidal bulges, resulting in high and low tides. Understanding these tidal patterns is crucial for predicting and preparing for natural disasters like flooding. NOAA uses tide charts and climate change data to predict flooding up to a year in advance. Meanwhile, in other news, India's democracy is facing challenges, with questions surrounding Prime Minister Narendra Modi's hold on power and concerns over cyber hacking and mass arrests. On a lighter note, for those seeking meaning in life, NPR has launched a new podcast called Wild Card, which combines a game show format with deep existential discussions. And in case you missed it, the science behind ocean tides has played a significant role in history, from influencing World War II battles to informing where we build our homes. Stay informed and engaged with these thought-provoking and timely topics.

    • TidesTides are caused by the gravitational pull of the moon and sun on Earth's water, with greatest forces during full or new moons. Humans have observed and studied tides for thousands of years due to their importance to civilization, particularly in coastal areas for food sources and transportation. Understanding tides helps us plan infrastructure.

      NPR Plus is a new way for listeners to support public media and access exclusive content related to their favorite NPR podcasts. During the conversation, the topic shifted to the science behind tides. Tides are caused by the gravitational pull of the moon and sun on the Earth's water. The greatest tidal forces occur during full or new moons when the Earth, moon, and sun are aligned. Humans have been observing and studying tides for thousands of years due to their importance to civilization. Coastal areas, which are often the sites of early civilizations, rely on tides for food sources and transportation. Understanding the patterns of tides helps us plan and build infrastructure along the coastlines.

    • Tide predictions during WWIIAccurate tide predictions during WWII were crucial for successful D-Day invasion coordination and helped the Allies achieve a significant military advantage

      During World War II, accurate tide predictions were crucial for the success of the D-Day invasion. Scientists used water level observations and complex machines with gears to predict tides, which helped the Allies coordinate landings at multiple beachfronts with varying tide conditions. Even small errors could have significant consequences, and the ability to predict tides decades in advance was a significant military advantage. This technology allowed for precise timing and coordination of the largest seaborne invasion in history, ultimately contributing to the Allied victory in Europe.

    • Tides and Military OperationsClimate change is causing more frequent flooding and shifting tide patterns, making military operations and infrastructure development more complex to plan and adapt to

      The relationship between tides and human activities, such as military operations and infrastructure development, can be significantly impacted by climate change. During historical military operations, like those involving paratrooper landings behind enemy lines, the timing of tides and the moon phases were crucial factors. However, rising sea levels due to climate change are pushing the baseline for flooding closer to shore, making it more frequent and requiring less extreme weather conditions to cause flooding. For instance, a Charleston, South Carolina, tide gauge that saw only one flood event per year a century ago now experiences approximately ten floods annually. This shift in tide patterns complicates planning for various activities and highlights the importance of adapting to changing environmental conditions.

    • Coastal Flooding PredictionNOAA's new model predicts coastal flooding up to a year in advance, using microwave radar instruments and real-time water level data from over 200 tide gauges.

      Even if individual tides may not be exceptionally high in a particular location, the overall sea level is rising, leading to more frequent flooding during high tides. NOAA has recently developed a model to predict coastal flooding up to a year in advance, providing valuable advance warning for affected communities. NOAA's tide measurements are now made using microwave radar instruments, which are about the size of a football and emit microwaves to determine water height. With over 200 tide gauges across the U.S., real-time water level data is constantly collected and averaged every six minutes for various applications, including ensuring safe port entry and monitoring storms and flooding.

    • Tidal energyTidal energy offers hope for renewable power in areas with strong currents through underwater turbines, addressing energy needs in remote locations despite challenges

      Tides not only bring about the ebb and flow of water, but they also offer hope in the form of generating green energy. In areas with strong tidal currents, such as the Bay of Fundy, scientists are exploring the potential to harness this power by installing underwater turbines. These turbines generate electricity as the water pushes against them, providing power to communities that may not have easy access to it otherwise. Despite the challenges of keeping equipment in the ocean, such as fouling and corrosion, tidal power has shown promise. This innovation not only addresses the need for renewable energy sources but also provides solutions for those living in remote locations. The ongoing research and testing in this field demonstrate the potential of tides as a significant contributor to the world's energy needs.

    How Israel Is Using Facial Recognition In Gaza

    How Israel Is Using Facial Recognition In Gaza
    After the Hamas attack of Oct. 7 triggered Israel's invasion of the Gaza Strip, hundreds of thousands of Palestinians began fleeing from the North of Gaza to the South. As they fled, many Palestinians reported passing through checkpoints with cameras. Israel had previously used facial recognition software in the West Bank, and some Palestinians reached out to The New York Times reporter Sheera Frenkel to investigate whether the same was happening in Gaza.

    Science correspondent Geoff Brumfiel talks to Frenkel about how Israel launched this facial recognition system in Gaza late last year with the help of private companies and Google photos.
