Q2 Why does so much duststack up in my room with windows closed 95% of the time? Jhansen Chonn, former Medical Laboratory Technologist 23-2-2017. I'm going to assume you never knew this, but dust is our dead skin cells. The largest organof our body is our protective skin. This stuff sloughs off all day, every day. Vacuum, dust and clean your room weekly, but twice a week wouldn't hurt. Remember also, too much dustcan attract dust mites in the droves of hundreds of thousands which cancause some people to react violently. Not really violently, people, areknown to be rather allergic to dust mites’ feces. You can't see them. But ifyou've been suffering from allergies, sneezing and red itchy eyes, those couldbe the darn pesky mites. Note about mites: they're ubiquitous and cannot be eliminated onlycontrolled. I vacuum weekly and I spray all my beddings and pillows with a 1:3dilution of vinegar and water with a few drops of lavender oil. I also washfrequently all my sheets in hot water. I can also use the vinegar solution onmy dogs to serve as a bath and to reduce dust mites on their skin. Plus itmakes them smell a bit nicer. My note- There can be dustparticles from surroundings also enter a room blown by wind. Q3 Why is the interestrate in provident fund (both for PPF and epf) gradually decreasing with time?Do you think in future the rate may become negligibly small and people may loseinterest in saving money in provident fund? A3 Prasanna Bhalerao M.Sc. in Electronics & Physics, Fergusson College, PuneFri I know and understand the sinking rate on standard retirement corpusbuilders such as PF, PPF, SSS, bank deposits, etc. It affects me too and makesme dejected if not frustrated. But it is a paradox situation. People want low rates when they want aloan but high rates on their deposits. On top of that, they don'twant heavy inflation. This can't happen. I remember that when I tookout my home loan way back in 1992, I was paying 16.5% interest! I had to provide 3 guarantors for a loan of ₹140,000.At that time NSC paid 12~13% interest on deposits and money doubled in 6 years.Inflation rate in those days was officially 9% but in real terms closer to 13–14%. Today, we can get a home loan at an average rate of 6.9% and sometimesas low as 6.75%. Inflation rate is 6%. Businesses can borrow at amuch lower rate. Lower borrowing rates benefit all. If borrowing rates are to below, inflation is to be low then deposit rates will be low also. You asked, will the lower rates cause people tolose interest in these schemes? This is certainly possible. In the US, there isequivalent of PF called 401K. There is hardly any interest on 401K and yetpeople deposit money in 401K plan. Why? Because people see a benefit there. So,all possibilities exist. My note- During 1991’s I couldget 16% interest on fixeddeposits. But my income was about 3000-00 rupees. Hardly no savings. One or twofixed deposits somehow made was for meagre Rs 15000 or so. Q4 How has technologystreamlined the Indian train travel industry? A4 Prashant Tiwari IndianRailways Enthusiast Apr 10 Technology has always replacedthe old methods of working over the years. Like others, Indian Railways has also adopted the new technologies overthe years which definitely made the working faster, easier & moreefficient. There are so many technologieswhich railways has adopted in terms of safety, signalling, operations,ticketing etc. Today Iwould like to highlight 3 such technologies which really changed the game forIndian Railways: 1 . HOG Technology We all have seen noisy generator cars at both the ends of almost all LHBtrains. Their work was to provide power supply to all the coaches mainly forac. The technology is known as EOG ( End On Generation) which is now replacedby HOG ( Head On Generation) . So, How this new technology has changed the game? Purpose of HOG is the same asof EOG but the source of power has been changed. EarlierEOG use to generate power through diesel generator installed in the car whichwas not just costly but also too noisy. Now, HOG simply takes the power from overhead wire andsteps down the voltage through transformer installed in the locomotive and thensupplies to all the coaches through attachable/detachable cable. 2. KAVACH ( Anti collisionsystem) Indian railways has recently adopted the new generation protection systemwhich simply provides a safety for head to head collisions. In the history, IRhas seen few head to head train collisions for example- Gaisal train accident.Such accidents costs alot in terms of people’s life. This technology will stop both the trainsautomatically well before if they are running on a same track towards eachother. 3. Services like Online ticketbooking, live running status, Rail madad etc. Few years back, we all use to run towards our nearest railway station tobook a ticket or to cancel it. It wasn’t easy at all . Now booking e-tickets has become wayeasier. You can book your train ticket in some clicks while sittingin your room. Live running status is available for last 6–7 years or even more but itwasn’t that accurate. Earlier it use to provide information with a delay of10–15 mins. With the new GPS in the Locotechnology, we get real time live running status of any train and leave ourhome for station accordingly. Rail madad is a portal operated by Indian railwaysto provide a quick support in a running running station. We often face problems like cleanliness, theft, watershortage, ac failure, safety and manymore. Earlier it wasn’t that easy to file your complaint officially. With Rail Madad you can simplyprovide some basic details with your complaint and any official who isresponsible mostly TTE will reach to you with in 20 mins. Q5 How do steamlocomotives pull a heavy load from a dead stop? Isn't there enormous stress on thepistons until the load gets rolling? Why don't the wheels just spin in place? A5 Loring Chien FormerPrincipal Engineer at Fortune 1000 Company (2002–2016)Mon The wheels won’t spin if the friction is high enough. A steam locomotivelike the UP Big Boy 4014 weighs about 1.2 million pounds (600 tons) which isweight on the wheels contributing to friction. Still, some locomotives had sandinjectors to spray sand on the rails in front of the wheels to help increase friction even more when startingfrom a dead stop, or uphill. As Kevin Neelley pointed out inthe comments, the train is not rigidly connected but has couplers so that the train only needs to get one car moving ata time on a very small scale. Q6 Why are spiders notconsidered insects whereas both of them are invertebrates? A6 Claire Jordan Degreein biology and folklore; programmer, shop owner, secretary on newspaper20h “Invertebrate” just means an animal which isn’t avertebrate. That’snearly all the animals there are. Animals are classified into major groupscalled phyla. Each phylum is radically different in form from every other. Iircthere are 36 animal phyla.Vertebrates are just a sub-group of a single phylum, the chordates. Insects and arachnids (spidersand their close relatives) are both in the arthropod phylum, but they are moredifferent in structure than you are from a stingray. Q7 What are peoplesupposed to do when a maid or housekeeper is cleaning? A7 Rukmini Hindupur Livesin Bengaluru, Karnataka, India (1986–present)Apr 2 First, the things I don’t do when the maid is there in my house. My maid is there in my house for around 15 minutes, never more than thatbecause, she only sweeps and mops the floor, which she does with mechanicalaccuracy, not a bit more nor less. We avoid eating at that time,we usually finish our breakfast before her arrival or we eat later. We avoid calls. Maids are notorious eavesdroppers. We don’t talk those thingswhich we want to be kept confidential. Our money, personal matters, plans etc. What we usually do is, read the newspaper or look at our phones. I keep an eye on her while doingso, because she is smarter than me, if she notices that I am not observing, sheavoids all inconvenient corners. She has a perfect way of moppingthe floor with lightest contact with the floor. I know there is no point telling her later that her work was sloppy. So Ihave to be alert while she cleans. I may be accosted with a question why I continue to employ her instead oflooking for a better one. In my forty years of experience, where I might have used the services ofdozens of maids, most of the maids are sloppy,inefficient. I may have had one or two efficient workers. So, now, in a city like Bangalore, where there is no dearth of work, weget only reluctant maids who are always on the lookout for better avenues. Q8 What is the mosteffective way to keep a computer screen dust free? A8 Ben Guy-Williams, Ilive with my computer. Answered Sep 15, 2021 I usually use a duster to dust.I use a damp cloth to do furniture, and a dry cloth to do electronics.

A9 Aditya Mishra Fell inlove with South Indian food Updated Wed Discovered the magic of south India through its food. When I first got to Chennai forwork back in 2013, I had many fears about adopting in Chennai. I had heard many negative reviews about food, people, andclimate. Food was the biggest fear for me as a north Indian staying in southIndia. My roommates were all from Tamilnadu. They mostly ate Idly, dosa,uthappam, Pongal, and other south Indian food. I was okay with occasional dosa but not the other ones. I did not knowabout cooking much, and the north Indian food available outside was bad. I feltmiserable. I wanted to get the hell outta there asap. I relied heavily on my cooking abilities which were limited to Maggi,oats, pasta, and Dal-rice. I had to take lunch at the office cafeteria. I was running out of foodoptions to pick from without hating it. I switched to sandwiches and juices forlunch. The lack of proper food andnutrients took a serious hit on my health. I felt bloated and tired all thetime. I was miserable and wanted to get out of Chennai. My roommates were very nice people, they got worried. They told me — “Aditya, you're going to be here fora few years, and it's better that you give south Indian food a try.” They took me to Sangeetha restaurant and made me try idly and uthappam.Then to Sarvana Bhawan and made me try different types of Dosa. For one week,they took me to many places and made me try all sorts of south Indian food. The last dish they made me try was egg Kothu Parotta, and it wasdelicious. I liked some of the dishes andtried them myself again. Slowly I started developing a taste for south Indian food. I started taking idly-vada forbreakfast. It did wonders for my digestion. I started eating lunch in authentic south Indian style. I used a bananaleaf plate and enjoyed a complete lunch meal. Sambhar rice, rasam, curd rice. I started eating a Yelakki (also known as baby banana) banana afterdinner, it helps in morning evacuation — No more constipation. I got addicted to Medu vada andtea. That combo was superb. I fell in love with the delicacy of south Indian cuisines. I even learnedto cook a few of them. My roommates were like --"Adithya, learn Tamil, and you will be a complete south Indian." I looked and felt great. I found the south Indian diet healthier. I stayed in Chennai for 5 yearsbefore moving to Bengaluru in 2018.I am working from home for the last 2 years and have been cravingauthentic south Indian food. I hope I have answered the question — how a north Indian manages to eatsouth Indian food? South Indian food is an acquired taste, it takes you to try it a fewtimes before you start liking it. My advice to North Indians inChennai is — Stop sulking and get out there and give south Indian food a try.Explore food. Explore life. You have to be open to new things. New experiences. It can do wonders. Younever know what you might fall for. Q10 How does the human fleshgrow and revitalize? A10 Ken Saladin Formerprofessor of histology (microscopic anatomy)22h Some people, when they say“flesh,” only mean muscle; others are referring to all human tissues. Anyanswer would depend on which meaning you have in mind. “Revitalize” is also unclear. I don’t know if you mean regenerating frominjury, or if you mean older organs or tissues becoming younger looking.If youwant to clarify, I will try to answer.
