Hello Friends, Welcome Back. I am back again with one another mysterious question of all times, "Do Dinosaurs Still Exists". The day I saw the movie "The Lost World", this question keep haunting me and kept me excited to find the answer for it and I researched a lot for the appropriate answer and what I conclude is I am going to share with you all. I hope I will be able to satisfy you all with my answer. Do dinosaurs still exist? The question may sound absurd. After all, conventional wisdom holds that these giant reptiles lapsed into extinction some 65 million years ago. Still, occasional reports from remote regions of the earth have kept the issue alive, if only to readers of tabloid newspapers and to the handful of scientists, adventurers, and nature writers who have tried to make sense of the accounts and, where possible, to investigate them. The idea of still-living dinosaurs has captured the public imagination for well over a century. Not only ...

Why Fog Lights Are Yellow !!!!!!!!!!

Hello Friends, Welcome Back, Its been quite long time since I shared my last post here with you all. So here I am again with you to share my knowledge on one more question that arouse in my mind due to the intense cold wave that is going on in northern part of India. Yesterday was the most foggy day in my city and I was going to the school in my car with the fog lights of my car on and guiding me the way through the intense fog, and suddenly a question stroked in my mind, that why fog lights are yellow in colour although if we notice in the wavelength series that is VIBGYOR, red colour has the largest wavelength, then why we use yellow light insted of red light in fog lamps. As per my understanding it is important for fog lights to be one color (rather than white, which is all colors) because the different wavelengths(colors) of visible light scatter off the fog droplets differently. This phenomenon is known as "dispersion," because the different colors of light in...

The Ancient Astronomers Who Measured Time Using Venus

  Chichen Itza observatory El Caracol ruins Mexico photograph There is a question that has quietly followed me through years of working in education. Why do so many students leave science classrooms believing that science is a collection of facts to memorise rather than a way of understanding the world? Over the years, I have reviewed countless lessons, textbooks, and learning materials. They are often carefully designed and scientifically accurate. A chapter on the Solar System might explain that Venus appears as both the Morning Star and the Evening Star. Another might describe the phases of the Moon or the changing seasons. Students are expected to remember these ideas, answer examination questions about them, and move on. Yet something is often missing. Rarely do these lessons begin with the question that must have fascinated the first person who looked carefully at the sky. Why does that brilliant object appear before sunrise for months, disappear completely, and then return a...
