If it was just 5 seconds , we wouldn't notice changes in our breathing. But do you know what would happen around us? Let's see.. Earth with no oxygen 1. Earth crust contains 45% oxygen. Without oxygen, earth's crust would crumble causing the ground to crumble and we would be in a free fall. 2. Buildings, bridges and concrete structures would crumble into dust. As oxygen is the binding agent for concrete. Buildings will fall 3. Cars would stop and planes would fall from sky as their combustion engines wouldn't work without oxygen. 4. Losing oxygen means losing almost 21% air pressure. This would cause our inner ear to explode, causing hearing loss. 5. It would also become darker suddenly because for sunlight to reach us, it needs to bounce off air particles like oxygen,dust,etc. No oxygen means fewer particles to bounce off, thus much darker. 6. All burning stoves in kitchen would stop as fire needs oxygen to burn. Are you hungry?? 7. All

U.S space agency National Aeronautics and Space Administration (NASA) has officially said moon lander Vikram has a hard landing and that its own orbiting spacecraft could not get clear picture of Vikram's crash site during its recent flyover. Vikram's possible crash site by LRO Camera NASA on Thursday night released a set of hazy images of the southern site where the lander probably crashed on September 7. Vikram's precise  location eluded the sharp camera of the Lunar Reconnaissance Orbiter (LRO) when it last flew over the probable site on September 17 . It captured a 150 Km wide area in the southern lunar highlands but the pictures were not clear as it was sunset and light had faded . Vikram lander is hiding in the shadow? A NASA statement said " It is possible that the Vikram lander is hiding in a shadow. The lighting will be favorable when LRO passes over the site in October and once again attempts to locate and image the lander ." This wa

In this post, we will discuss 5 scientific ways to become a topper of your class. Do you promise yourself daily that “Today I will study 8 hours, but ends up doing nothing and regrets why I didn't study today, okay I will study tomorrow promise” and this cycle keeps going. This is called procrastination. So read this post till last to overcome these problems. 1. Plan your day in advance There is no point in studying without proper planning . This is the only difference between a topper and a runner up. So before going to sleep just make a list in your mind regarding next day tasks. For example- 2 topics of this chapter, school assignment, physical exercise, etc, and always prioritize important tasks first then complete them in order. For example- 2 topics of a chapter and school assignment are must but if you are running out of time, you can skip exercise today. Priority 1- 2 topics of chapter. Priority 2 - school assignment. Priority 3- physical exer

Chandrayaan-2 mission was launched on 22 July and its expected date of land was 7 September but unfortunately ISRO lost the communication with its lander (Vikram). Vikram's normal performance was observed up to an altitude of 2.1 km. Subsequently, communication from the lander to ground stations was lost. Prime minister Narendra Modi with ISRO'S chairman Dr. K.Sivan. What happened in those last 15 minutes? The expected time of Vikram to land on moon was 1.55 A.M, but at 1: 39 am, Vikram was travelling at a speed of around 21,600 kmph or 6 km per second. The speed of a commercial airplane is around 900 Kmph and by comparing Vikram’s speed with it, Vikram was travelling 25 to 30 times speed of the airplane. Immediately after 1:39 am, in the last 15 minutes, came a challenge for ISRO scientists to lower down the speed to 7 Kmph. From 21,600 Kmph to 7 Kmph was always going to be a tough task in order to land safely without crash or any other technical failure.
