Q1         Are apes more closelyrelated to monkeys than humans? If so, why do 
we have a common ancestor withmonkeys but not with apes (gorillas and 
chimpanzees)?

A1         Claire Jordan, Degree inbiology and folklore; programmer, shop 
owner, secretary on newspaper 51m

No - in fact humans are a typeof ape. And of course we have common ancestors 
with otherapes.

30mya - Simian primates split into Platyrrhines (called New World 
monkeysalthough the first one lived in North Africa) and Catarrhines.

25mya - Catarrhines split into Cercopithecidae (Old World monkeys) 
andHominoidae (apes).

15mya - Hominoidae split into Hylobatidae (gibbons and siamangs) andHominidae 
(great apes).

11mya - Hominidae split into Ponginae (orangutans) and Homininae.

8mya - Homininae split into Gorillini (gorillas) and Hominini.

 

7mya - Hominini split into Panina (common chimps and bonobos) andHominina 
(humans and proto-humans).

A2         Akash Bahetra, FormerStudent Updated 5y

Mobile phones can save your life- Shocked ? Confused ?

Yes !! Mobile phones Can actuallysometimes save human's life .

I was just going through the news and i saw a women claiming that heriphone 
saved her life at the Manchester Sucide Bombing Incident.

You can See this post by Steve Bridgett

Q3         Can you tell about Desertof Ghost ship conversion?

A3         Kathleen Pennell's Posts,Postedby Jo Mburu  Fri

Desert Of Ghost Ships only 30years ago, this was home to our planet’s 4th 
largest inland water mass; an ancient sea so vast, even Alexander the Great 
wrote of his struggles to cross it.

In the 1960s, the Soviet Unionbegan diverting the Amu Darya and the Syr Darya; 
the two major rivers whichsupplied the vast majority of water to the Aral Sea, 
in order to irrigate theirmassive cotton plantation complex.

Q4         The US standard railroadgauge (distance between the rails) is 4 
feet, 8.5 inches. That's an exceedinglyodd number. Why was that gauge used?

A4         Emily PalmerApr 1

Well, because that's the way theybuilt them in England, and English engineers 
designed the first US railroads. Why did the English build them like that?

Because the first rail lines werebuilt by the same people who built the wagon 
tramways, and that's the gaugethey used. So, why did 'they' usethat gauge then?

Because the people who built thetramways used the same jigs and tools that they 
had used for building wagons,which used that same wheel spacing. Why did the 
wagons have that particular odd wheel spacing?

Well, if they tried to use anyother spacing, the wagon wheels would break more 
often on some of the old, longdistance roads in England . You see,that's the 
spacing of the wheel ruts. So who built those old rutted roads?

Imperial Rome built the first long distance roads in Europe (includingEngland ) 
for their legions. Those roads have been used ever since.

And what about the ruts in the roads?

Roman war chariots formed theinitial ruts, which everyone else had to match or 
run the risk of destroyingtheir wagon wheels. Since thechariots were made for 
Imperial Rome , they were all alike in the matter ofwheel spacing. Therefore 
the United States standard railroad gaugeof 4 feet, 8.5 inches is derived from 
the original specifications for anImperial Roman war chariot. Bureaucracies 
live forever.

So the next time you are handed a specification/procedure/process and 
wonder'What horse's ass came up with this?', you may be exactly right. Imperial 
Romanarmy chariots were made just wide enough to accommodate the rear ends of 
twowar horses. (Two horses' asses.)

Now, the twist to the story:

When you see a Space Shuttle sitting on its launch pad, there are two 
bigbooster rockets attached to the sides of the main fuel tank. These are 
solidrocket boosters, or SRBs. TheSRBs are made by Thiokol at their factory in 
Utah . The engineers whodesigned the SRBs would have preferred to make them a 
bit fatter, but the SRBs had to be shippedby train from the factory to the 
launch site. The railroad line from thefactory happens to run through a tunnel 
in the mountains, and the SRBs had tofit through that tunnel. Thetunnel is 
slightly wider than the railroad track, and the railroad track, asyou now know, 
is about as wide as two horses' behinds.

So, a major Space Shuttle design feature, of what is arguably the world'smost 
advanced transportation system, was determined over two thousand years agoby 
the width of a horse's ass.

And you thought being a horse's ass wasn't important? Ancient horse's asses 
controlalmost everything.

Q5         The Great Wall of Chinatook 2,500 years to make. Considering the 
resources and technology available today,how long would it take if the wall was 
made today?

A5         CaiLei, Lives in China(1975–present)Sat

The Great Wall is not a singleproject, but a series of projects.

Each dynasty in China built its own Great Wall.

There are Qin Great Wall, HanGreat Wall, Tang Great Wall...Ming Great Wall, 
some are expanded on the basisof the original Great Wall, and some are newly 
built.

The Qin Great Wall is only 1 meter high, it can only stop cavalry, and itis 
mostly built with gravel. Distributed in Gansu, Ningxia Hui AutonomousRegion, 
Inner Mongolia Autonomous Region, and even where the Qingchuan Riverenters the 
sea in North Korea. The Qin Dynasty was from 221 BC to 227 BC, Afterall, the 
constructiontechnology at that time was not very developed, and the story of 
MengJiangnu crying and causingthe Qin Great Wall to collapse is just a 
fictional rumor;

The Great Wall of Xinjiang inthe Tang Dynasty was mostly rammed earth, and 
Xinjiang is arid and has little rain, so the choice of localbuilding materials 
is limited;

The Great Wall of the MingDynasty was built with glutinous rice as an adhesive 
and bricks. What you see when traveling in Beijing is usuallythe Great Wall of 
the Ming Dynasty.

My note- Informative answer for me.

Q6         What is obsolescence, andwhat are some examples?

A6         Loring Chien, FormerPrincipal Engineer at Fortune 1000 Company 
(2002–2016)Mar 31

A Ford model T car is obsolete.At one time it was state of the art and a 
bargain at the price.

But todays cars are faster, safer, more comfortable, more practical. 
Morestylish and meet umpteen safety regulations for crash safety, fuel 
economy,lighting, seat belts, airbags, Not to mention things that improve our 
driving experience, GPS,adaptive cruise control lane departure, auto-braking 
and in some cases selfdriving. Auto parking, TPMS, heated seats air 
conditioning and heating,intermittent and multispeed wipers, auto headlights, 
radio entertainment youname it.

Not that people don’t ever driveModel T for nostalgia sake, but its no longer a 
daily driver. But its obsolete,can’t meet standards and can’t meet expectations 
for a car anymore.

When a thing starts to become obsolete, it is in the stage ofobsolescence. 
Today, film camerasmeet that. They are still used but mainly for nostalgia. 
Incandescent bulbs inobsolescence, you can still buy a few, but LEDs have 
replaced them.

Q7         How can we see divergingsun rays if the sun were really 93,000,000 
miles away?

A7         Wayne Boyd, Philosopher,published author, science writer. Apr 6

These train tracks appear to converge, do they not? It’s calledperspective.

VP in this image is called the Vanishing Point. Neither the road nor thetrain 
tracks actually converge into a point. They just look like they do because the 
farther the things are, thesmaller they appear.

The Sun is 93 million miles away. All the sun rays point to the sun’sdisk, 93 
million miles away. Althoughfrom this position it looks like the rays of the 
Sun are not parallel,they are absolutely parallel. It is perspective that makes 
them appear toconverge at a vanishing point.

Q8         What are some of theinteresting facts about India?

A8         Angel Singh, Lives inLucknow, Uttar Pradesh, India 
(2004–present)Updated 1y

1. Only 3% of Indians pay Income Tax ie. around 40,579,268 (according tothe 
population in 2019).

2. The number of people (ie. around 23 million) travelling on India'strains 
each day is equal to the population of Australia.

3. India is the 2nd populouscountry and also the 7th largest country in the 
world.

4. India has more over 300,000 mosques.

• Actually there are moremosques in India than any other Islamic country on 
Earth.

5. There's a village in Maharashtra named Shani Shingnapur that has nodoors and 
locks in the houses.• Villagers believed that God Shani, the God ofSaturn, will 
punish anyone attempting theft.

***6. The World's Only FloatingPost Office is in Srinagar's Dal Lake in India.

• It also has a museum insideand being the Only Floating Post Office in the 
world, makes it a unique pieceof architecture.

7. There's a village named Snapdeal.com Nagar in Muzaffarnagar districtin Uttar 
Pradesh.

• It was named so, as the e-commerce website installed 15 hand-pumps inthe 
village so the villagers do not have to walk miles to fetch water.

You can see the Snapdeal logo sticked everywhere in the village.

8. The Indian National Kabbadi Team was the only team to won all theKabbadi 
World Cups before the game played against Iran in 2020.

9. Snakes & Ladders wasoriginated in Ancient India.• It was used as a part to 
teach moral instructionsand karma in early centuries.

10. The World's Highest Rail Bridge in being built in Jammu&Kashmir.•It is 
being constructed ata height of 359 metres from the riverbed of the Chenab 
river and is 1.3km longand 35metres higher than the Eiffel Tower.

11. A lake named Lonar Lake in Maharashtra was formed by a meteor 52,000years 
ago.

12. Mawsynaram is the wettestplace on Earth with 11,874mm of rain anually.

13. India was the first country to produce sugar.

14. Arithmetic, Geometry, Algebra and Trigonometry originated from India.

First, thankyou for this! It’s my first answer to get so many views andupvotes.

Second, for the point 1st point, that value can't be 100% true. Hence,it’s a 
approx value calculated with the population in 2019, Please note 2019.

Third, for the 14th point, I know I got wrong in the Algebra part. So I'msorry 
for that.

My note- If my memory is correct there are floating post offices still 
inAlleppy District in Kerala.

Q9         Do cats know what we are?Do they think we're some kind of big cat? 
Or just a very weird creature givingthem food.

A9         All about Cats, Answeredby John Holt Jan 31

When kittens first open theireyes, they don’t perceive us as much more than a 
disembodied hand thatinteracts with them.

As they mature they begins topick up on more complexities of what we are and 
begin to adjust their behavioraccordingly. Despite this theyinnately realize we 
are companions and caregivers, but also a differentspecies.

A great example of this is how they communicate with us. The majority of feline 
to felinecommunication is based on body language, yet they learn fairly quickly 
ourbrains don’t work that way and begin meowing for specific cues.

This is my Sadie girl, she has a meow for “food”, one for “getting low 
onwater”, one for “get out the toys”, and one for “I want scritches.” She 
hasrecognized I don’t readfeline communication methods as well as another cat 
would and has adjusted herbehavior accordingly.

Q10       Which European countrieshave a good railway network with maximum high 
speed trains, such as French TGVor German ICE, etc.?

A10       Nicholas Stone, Life longinterest in trains. Sat

Four European countries haveparticularly well developed networks of dedicated 
high speed passenger lines. All feature running speeds of greater than 200km/h, 
station passing loops, grade separated junctions and advance trafficmanagement 
systems. Each has their own characteristics. I have travelled on allfour 
networks many times.

Italian high speed passengerlines are essentially linear.There is one near 
continuous high speed line from Turin to Salerno - via Milan,Bologna, Florence, 
Rome and Naples. This connects almost all of Italy’s majorpopulation centres - 
with buoyant passenger volumes. Consequently, there aretwo operators. State 
owned Trenitalia offering Le Frecce brand of high speedservice and the 
privately owned Nuovo Trasporto Viaggiatori (NTV).

Operating on the high speed Italian rail network, an NTV train with 
thedistinctive .Italo branding. On board, there are three travel classes: 
smart,prima and club.

France has a mainly radial highspeed network with four routesfanning out of 
Paris. State owned SNCF operates the world famous TGV train withtwo travel 
products. There’s the full service inOui trains and the budgetOuigo. SNCF has a 
majority stake in the Eurostar-Thalys international high seedservice, with 
Paris Gare du Nord departures to London, Brussels, Antwerp,Rotterdam, Amsterdam 
and Cologne.

Spain also has a mainly radialnetwork, centred on Madrid.There are several 
noteworthy features. Dedicated high speed lines are built tothe 1,435 mm gauge 
rather than Iberian 1,668 mm gauge. Special trains travelover gauge changers at 
slow speed between the two networks. There is nowparticularly competitive 
domestic high speed passenger rail market, with Iryoreceiving special praise.

A high speed Iryo passenger train in Spain. The trains offer three 
travelclasses and six fares. The rolling stock is identical to the Italian le 
Freecefleet, reflecting ownership. Iryo is jointly owned by Trenitalia, Air 
Nostrumand Globalvia.

The German high speed networkand operations differ significantlyfrom the above 
three. A mixture of upgrade and new build links pairs of citiesrather than the 
radial or linear networks elsewhere. The principal operator isthe state owned 
Deutsche Bahn’s InterCity Express (ICE) service - offering twotravel classes 
and often full dining. Seat reservations are not mandatory.These long distance 
ICE service will use a mix of new build, upgrade andclassic tracks as they 
cross Germany.

In my opinion, the German and Italian high speed passenger trains areamong the 
best in Europe. Both offer higher standards of passenger comfort anddining 
cars. Part of the Italian high speed through Tuscany, Umbria and Laziois 
particularly scenic.
