Q1                 Can front-load liquid detergentbe used in a top load washing 
machine?

A1          Gopala Krishnan,Former AssistantGeneral Manager 1996-2004 at 
Department of Telecom (1966–2004)0y

InIndia nowadays we get detergent liquids from different companies suitable 
forfront load, top load and bucket hand wash.

Olden days whenpressure cooker was introduced it was provided with  a bottom 
plate, containers for differentcooking items etc.Gradually house wives started 
removing them and place one bigvessel for rice cooking and on it if necessary 
an oval plate to cook dhal,potato etc.

Latercompanies stopped giving bottom plate and separators.

Similarly home makers started using front load for topload, bucket etc., and 
interchanging and  it come as a practice and companies alsostarted  provide a 
common type ofdetergent liquid .

Q2         What is one fact that you know is truebut still blows your mind?

A2          Vipul Mehta

If you are payingin cash or through your debit card for your purchases, you are 
subsidizing therewards for customers who pay through their credit cards.

Yes. That’s true.This is how it works:

Credit cardcompanies (or banks) pay rewards to its users in order to 
incentivize the usageof their company’s credit card. These rewards usually come 
in the form ofreward points/miles etc. etc.

My note- Mainadvantage I felt by credit card is the option to pay bill after 45 
days. Onemergency it provides for paying hospital bills.

 (Now, at this point, one may ask why thecredit card companies want us to pay 
through their credit card. The answer to this is that these companies charge 
money fromthe merchants who accept the credit card at their store. This charge 
variesfrom a seemingly innocuous 2% to as high as 4% of the transaction. This 
isreferred to as ‘merchant fees’.)

The rewards thatthe credit card users get from the credit card issuer companies 
is partly paidoff by the income that these companies get from the merchants 
i.e. from the merchant fees.

The merchants, who are there to make profits and earn alivelihood, shift the 
burden of merchant fees from themselves to the customersby incorporating the 
merchant fees in the prices of the products.

Now, theoretically,the merchants should only charge the extra amount from 
credit card users onlyas they are the ones forcing the merchants to pay high 
fees. However, thisrarely happens. The merchants, to cover their merchant fees, 
usually increasethe prices across the board for all the customers irrespective 
of the mode ofpayment.

What this causes isthat the credit card user who gets handsome rewards from the 
credit cardcompanies is compensated for the higher price paid by him/her. 
However, the customer who paid throughcash(/debit card/basic credit card with 
no rewards) lost out on money as theyalso had to pay a higher price on the 
products without getting anything inreturn.

In this scenaro,

Merchants=No profit/no loss as they passed the burden of merchant fees on to 
thecustomers.

Creditcard companies/banks= In profit, as they get merchant fees from the 
merchants.

Credit card users=In profit, as they usually get handsome rewards

Customers who paid throughcash/debit= the people who lose out.

Q3         Is it possible for a plane to landwithout touching the runway?

A3          Rebecca Williams, Experience inAviation Wed

It is possible fora plane to land without touching the runway. This is called a 
**touch-and-golanding**. In atouch-and-go landing, the plane touches down on 
the runway, but it does notcome to a complete stop. Instead, the pilot applies 
the throttle and takes offagain immediately.

Touch-and-golandings are used for a variety of reasons. They are often used by 
pilots during training to practicelanding. They can also be used to check the 
condition of the runwayor to reposition the plane on the runway.

To perform a touch-and-go landing, the pilot will followthe same steps as they 
would for a normal landing,but they will apply the throttle sooner and take off 
again before the planecomes to a complete stop.

Touch-and-golandings can be a bit tricky, but they are a valuable skill for 
pilots tolearn. They can help pilots to become more proficient at landing and 
to developtheir skills in a safe environment.

Q4         Should I drink tea after eating fruits?

A4          Sheetal Kushwah, 7 years of experiencein natureopathy 6h

There is no particular disallowdrinking tea in the wake of eating natural 
products.As a matter of fact, consumingtea in the wake of eating fruits is by 
and large protected.Notwithstanding, it's essential to take note of that the 
impacts might shiftrelying upon the sort of products of the soil you consume.

The following are a couple of interesting points:

Assimilation: Certain individuals accept thatdrinking tea following eating 
organic products can obstruct processing. Thisconviction originates from the 
idea that tea's tannins can disrupt theassimilation of specific supplements. Be 
that as it may, the effect of tea onabsorption is commonly negligible, and it 
might shift from one individual toanother.

Iron retention: Certain organic products, forexample, citrus organic products, 
are plentiful in L-ascorbic acid, whichimproves iron assimilation. Then again, 
tea, especially dark tea, containsintensifies that can hinder iron retention. 
Assuming you are worried about ironlevels, you should abstain from drinking tea 
just in the wake of polishing offiron-rich natural products or feasts.

Individual inclinations: At last, whether you ought todrink tea subsequent to 
eating organic products relies upon your own inclinations.Certain individuals 
partake in the blend, while others could think that it isless engaging. In the 
event that you partake in the taste and experience ofhaving tea after organic 
products, there is no mischief in doing as such.

Hydration: Drinking tea can add to your generalliquid admission, which is 
significant for remaining hydrated. Organic productsadditionally contain water, 
so drinking them along with tea can additionallyadd to your hydration levels.

All in all, thereis no severe vote down drinking tea in the wake of eating 
natural products. Itby and large boils down to individual inclination and 
individualcontemplations, like processing and iron ingestion. In the event that 
youpartake in the blend and it causes no uneasiness, there is no great 
explanationto stay away from it.

of a reputed service company.

Q6         Is there any way to create ice withoutrefrigeration?

A6          Achintya Paradkar, Learning PhysicsEvery day! 8y

No. It is not possible if the atmospheric temperature isabove freezing point of 
water. You might use anyother refrigeration techniques like "Vapor Absorption 
Cycle", "SolarRefrigeration", "Vacuum Refrigeration" or "LiquidNitrogen" if you 
don't wantconvention refrigerator but in order to form ice refrigeration is 
must.

The best way is to use a vacuum pump to reduce thepressure inside the water 
container till the boiling point is reached.This will cause the water to 
evaporate absorbing latent heat of vaporisation.Due to this removal of heat, 
the remaining water droplets will crystallizeforming ice.

P.S. Just make surethat this newly formed ice doesn't get sucked inside the 
vacuum pump.

Q7         How was ice made when there was nofridge?

A7          PREETI PRABHA, We provide Wash, Dry& Fold within 2 hours per 
Individual. Wed

Before the invention of refrigerators, people usedvarious methods to make ice 
and keep things cold.

Here are a fewhistorical methods:

Icehouses: These were structures or undergroundchambers specifically designed 
to store ice. During winter, ice would beharvested from frozen lakes, rivers, 
or ponds and stored in these insulatedspaces. The icehouses were well-insulated 
with materials like straw, sawdust,or even cork to prevent melting. This stored 
ice would be used throughout theyear for preserving food or for cooling drinks.

Iceboxes: Iceboxes were wooden or metalcontainers with insulated walls. They 
had a compartment for storing ice at thetop and a lower compartment for keeping 
food. A block of ice would be placed inthe top compartment, and the cold air 
would circulate downwards, keeping thelower compartment cool. The ice would 
need to be replaced regularly as itmelted.

Natural Ice Harvesting: In colder climates, peoplewould wait for lakes and 
rivers to freeze over during winter. They would thencut blocks of ice from the 
frozen bodies of water and store them in icehousesor cellars with good 
insulation. Sawdust or other insulating materials would beused to minimize 
melting.

Ice Delivery: In urban areas, ice would beharvested from frozen lakes or 
imported from colder regions and transported tohouseholds and businesses. Ice 
delivery companies would use ice-cutting tools,insulated wagons, and icehouses 
to transport and store the ice. Ice would bedelivered to homes, restaurants, 
and other establishments on a regular basis.

Q8         Was there something that particularlybothered Hitler?

A8          Ayomikun Abraham,un 26

Yes, there were several things that particularlybothered Adolf Hitler, the 
dictator of Nazi Germanyduring World War II. 

One of the major concerns for Hitler was the Treaty ofVersailles, which imposed 
harsh reparations andterritorial losses on Germany after World War I. Hitler 
viewed the treaty as ahumiliation for Germany and believed it was unfair. He 
was driven by a desire to overturn the treatyand restore Germany to its former 
glory.

Hitler also held strong anti-Semiticbeliefs and harbored a deep hatred towards 
Jewish people.He blamed Jews for various societal problems, such as economic 
struggles andthe loss of World War I. This hatred manifested in the Holocaust, 
wheremillions of Jews and other minorities were persecuted and 
systematicallymurdered under Hitler's regime.

Furthermore, Hitler was obsessed with achieving racialpurity and advancing the 
Aryan master race ideology.He propagated ideas of racial superiority, aiming to 
eliminate those heconsidered racially inferior, including Jews, Romani people, 
disabledindividuals, and others deemed undesirable.

Hitler's expansionist ambitions and quest for Lebensraum(living space) for the 
German people were also significant concerns for him.He sought to conquer vast 
territories in Eastern Europe to establish Germandominance and create an empire 
that would endure for centuries.

Hitler's beliefs and actions were deeply rooted inhatred, bigotry, and a quest 
for power. His ideologiesand the atrocities committed under his leadership have 
had a lasting impact onhistory and serve as a stark reminder of the dangers of 
extremist ideologiesand totalitarian regimes.

 Q8        Whichinvention has a curious story behind it?

A8          Deep Thakar, Engineer | Observer |Photographer | AstrophileJun 25

One invention witha curious story behind it is the Slinky. The Slinky is a 
popular toy that consists of a helicalspring that can "walk" down stairs or 
slopes when pushed. It was invented by Richard James, a naval engineer, in the 
early1940s.

The story goes thatRichard James was working on designing springs that could 
stabilize sensitiveequipment on ships during rough seas. One day, he 
accidentally knocked one of the springs off ashelf, and he watched as it 
gracefully "walked" down a series ofbooks, a stack of magazines, and finally 
onto a tabletop. This inspired him with the ideaof turning the spring into a 
toy.

Richard James and his wife, Betty James, spent yearsperfecting the toy and 
eventually came up with the name "Slinky"because they liked how it sounded. 
They foundedJames Industries to manufacture and sell the Slinky, and it was 
firstdemonstrated at a Gimbelsdepartment store in Philadelphia in 1945. 

Initially, the Slinky didn't sell well, but the Jamesespersisted and eventually 
got a breakthrough when they persuaded a buyer from alarge department store to 
allow them to demonstrate the toy in-store.The demonstration was a huge 
success, and they soldout their entire inventory of 400 Slinkys in just 90 
minutes.

The Slinky went onto become an iconic toy, captivating generations of children 
and adults alike.Its simplicity and unique movement continue to fascinate 
people to this day,making it a classic and beloved invention with a 
surprisingly humble andaccidental origin story.

Q9         What did money look like during theBritish Raj?

A9          Gopalkrishna Vishwanath, Have alwaysbeen interested in History, 
once I didn't have to learn it formally Updated Mon

I was not born during the British Raj.

But I remember thatmoney minted during the British Raj was still in circulation 
and was validcurrency during my childhood.

Mostof the money in circulation used for common day-to-day expenditure was in 
theform of coins and not currency notes.

Even a one Annacoin worth 6 paise had great value.Here is a coin minted in the 
year 1915.Note that the value is writtenin English, Hindi, Urdu, Telugu, and 
Bengali.

16annas were equal to one rupee.

In 1959 I felt likea pampered 10-year-old kid when my mom yielded to my nagging 
and parted withthis coin so that I could buy a packet of roasted peanuts from 
the pavementhawker.

This coin was soprecious that even beggars would hesitate to ask for one 
anna.They wouldrequest at most one paisa which was a fraction of one anna.

You could hear thembegging in a pathetic voice “Babujee, ek paisa de do. 
Bhagwaan aapka bhalakarega “ (Translation : Sir, please give me one paisa. God 
will favor you”)

This was how acoin, double in value looked like. You could buy a Masala Dosa at 
an Udupirestaurant in Mumbai with this coin.

And if any one ofus, little schoolboys, had this coin in our pockets, we would 
be called “rich”!

How times have changed!

Edited to add:Ithank Ajay Kumar Bisoi for retrieving this precious picture of a 
“one pice”coin. This was the lowest denomination coin those days.

Edited to add on June 26, 2023

I thank Shri R.Chandrasekharan Kannammal for these additional images in his 
comment.

My note- I still recollect, I was afraid of collecting100 rupee currency in a 
public auction in 1974’s.  My salary was received  above 350-00 rupees, but in 
smallerdenominations.
