Napne Waterfall
Napne Waterfall, also known as Sherpe-Napne Waterfall, is a beautiful, perennial waterfall located in the Konkan region of Maharashtra, India.
Maharashtra’s first glass bridge has been built over Napne Waterfall, offering visitors a thrilling and immersive experience. This transparent bridge allows you to walk directly over the gushing water and enjoy panoramic views of the waterfall and the surrounding valley

Brownian Motion and Einstein
In 1905, Albert Einstein explained Brownian motion, the random movement of small particles in a fluid due to collisions with surrounding molecules. This explanation was one of four groundbreaking papers in his annus mirabilis (miraculous year).
Mechanism and Technology In 1905, Albert Einstein explained Brownian motion, the random movement of small particles in a f luid due to collisions with surrounding molecules. This explanation was one of four groundbreaking papers in his annus mirabilis (miraculous year). Over a century later, scientists at the California Institute of Technology (Caltech) have achieved a technological breakthrough by developing a non-invasive imaging system that can record molecular motion in real-time at an unprecedented scale—down to Uses ultrashort laser pulses to illuminate the sample in a cuvette. Digital micromirror device (DMD): Shapes the laser light beam. Works like assembling a jigsaw puzzle from a few pieces. Streak camera: Converts light photons to electrons. Captures streak patterns indicating pulse duration, revealing molecular size. Achieved imaging speeds of hundreds of billions of frames/seconds. Applications and Future Impact This new imaging method is expected to revolutionize various fields: Biomedical Research: Studying molecular interactions and disease mechanisms. Early Disease Detection: Observing changes in biomolecular structures. Drug Development: Monitoring drug delivery and molecular responses in real-time. Material Science: Designing and testing nanomaterials. Combustion and Atmospheric Science: Understanding particle behavior in gas environments.
