This is such an interesting DIY project. I am kind of waiting now for my phone to become old enough and thus 'eligible' for this experiment :D. Although I am a little skeptical about a few requirements like finding the right kind of parts dimensions wise, and drilling/creating a hole etc. but would like to wing it nonetheless :).Thanks sir, for writing this post.

Thank you sir, for sharing this information with us. It is indeed an eye opener.

On It glitters. Is it Gold?

Thanks for sharing such a simple yet intriguing post. My answers for the quiz:1. No effect: both numerator and denominator would be getting multiplied by the same fraction (0.9), thus canceling its effect2. No change: same reasoning as above. however, had we be using the actual volume of the object instead of the weight reading as its proxy, then the density reading would have been lower3. No change, given that we know the density of sea water: as per my understanding sea water has higher density than water, which means that for the same volume (filled up to the same level in the beaker), displaced sea water's weight reading will be higher (higher density ~ higher mass for a constant vol). in fact it will be higher by the same proportion as the density is and thus the ratio of (displaced liquid weight/density of liquid) will be the same as in the case of water. thus, neither the numerator (weight of object) nor the denominator (volume calculated according to the above mentioned logic) would change, resulting in no change in density reading4. I can think of the following prerequisites for conducting a successful experiment of determining density using the above stated methodology: a) Know the density of the liquid being used for immersion since we are using displaced liquid's weight readings as the proxy for the object's volume. b) During the immersion, ensure that no entity other than the object itself, displaces the liquid. That is why there should be no hollow spaces otherwise it will not just be the object but also air displacing the liquid. c) Immerse the object completely otherwise the displaced liquid would only reflect the partial volume. d) The object should not touch the beaker's walls at any times otherwise there would be an additional normal (N) from that surface.Looking forward to the answers and learning from them 🙂

Thank you so much sir, for such kind words. Looking forward to your next post.

On My Near Ghost Experience

Interesting post, thanks for sharing this experience.It reminds me of my childhood days when I stayed in a college campus, in Kota. The place, its ambience and spirit were all very similar to what you've described in the above blog. It was far from the hustle-bustle of the city and was built by clearing out the forest land situated at the cliff of a canyon of Chambal river. Owing to this geological history, the campus was sometimes visited by exotic members of the fauna like hyenas, bears, leopards, jackals etc. We were so used to of finding snakes and scorpions in our quarters during the monsoon season that I am still habituated to look down, behind a door, when I open one. We used to have a square shaped, tin plate kind of a thing to block the gaps in the windows; wow haven't seen that in a long time, wish I had pictures.I witnessed similar light and sound shows as the one you've described, many times. I am not a sound sleeper anyway and I used to wake up, scared, only to be hushed back to sleep by Maa or my elder sister. The Babool trees are rather nasty at casting creepy shadows at night; that, paired with a cry of a kitten or an owl was enough to convince me of a ghostly presence, specifically searching for me. But, it's amazing how this fear lasted only during the night, for in the day, I was the brave one, boasting about my life in the wilderness at the school.I wonder if there ever was a ghost and if it ever attended my brag sessions, waiting for the night to fall!
