Q1         What are some of the greatest examplesof presence of mind?

A1          Apar Kaushik, Studied at The Instituteof Chartered Accountants of 
India (ICAI)6y

Once Billgates advised warren buffett to invest in tech companies like 
microsoft , appleetc .

And for thatbill gates is trying to explain him that entire world is going to 
be changed incoming years i.e we can able to talk anywhere in world through 
internet,introducing touchscreens in mobile phones , video conferencing , 
laptops andwhat not.

Warrenbuffett(WB) listens to him carefully and after that asked bill gates(BG) 
; thatif people are introduced to these technologies , then are they going to 
stopeating chewing gums?

BG: ofcourse not

WB: are theygoing to stop drinking coke?

BG: NO

WB: ok theni’ll choose chewing gums and coke , and you choose technology.

And fromthen WB knew that sales of these companies are never going to be 
effectedwhether people are introduced to the technology or not .

Q2         Has the Shinkansen ever had anaccident?

A2          Shubham Bhargava, Consultant atHigh-Speed Rail 8mo

No, TheShinkansen which is Japan's bullet train rail network, has never had 
anaccident in its 59-year history.

 

In case ofearthquake, Shinkansen operation is stopped immediately when the 
seismometersdetect the primary wave of an earthquake. Since 2005, JR East has 
increased thenumber of seismometers along its lines and improved its estimating 
methods totry to stop train service as soon as possible in the event of an 
earthquake.

Also, It ispassing through one of the beautiful places. Mount Fuji can be seen 
from theTokaido Shinkansen between Tokyo and Osaka. When coming from Tokyo, 
themountain appears on the right side of the train and is best viewed 
aroundShin-Fuji Station, about 40-45 minutes into the journey.

Q3         Who is believed to have created godslike Brahma, Vishnu, and Shiva 
in Hindu mythology?

A3          Anurag Mishra,Have been studying andunderstanding Hinduism since 17 
years Feb 10

As per theSmarta tradition established by Bhagwan Adi Shankaracharya who is 
known for there-establishment of Sanatan Dharma to its original form, there is 
only one God,Gyani Jans call him Para-Brahma, Yogi Jans call him Paramatma and 
Bhaktas callhim Bhagwan.

Smarta Tradition tells that this one Para-Brahmamanifests himself in five forms 
which are Vishnu, Shiv, Brahma, Ganesh, and AdiShakti.

Brahma,Vishnu, and Shiva are parts of the Trinity in Hinduism. Brahma takes 
care ofthe creation, Vishnu is the preserver(also called Vishwambhar) and Shiva 
is theGod of destruction.

There can beno preservation, if there is no creation and no destruction if 
there is nopreserved Creation. SoBrahma, Vishnu, and Shiva are one and the 
same. As per the Smartatradition, if you worship any of the above-mentioned 
five menifestations or theirincarnations, you are worshiping the same 
Para-Brahma and all you see is onlyhis manifestation but due to Maya appears to 
be duality.So, the answer to your question is no one createdBrahma, Vishnu, and 
Shiva.

 

Q4         Since humans have been around for manythousands of years, why is it 
only in the last 400 years that they have startedusing electricity and invented 
things like cars and planes?

A4          Mats Petersson, Skaterboy many yearsago Mar 23

The short answer is “we didn’t have enough wealth andspare time before then”.

Long answer:

So humanshave been the current species Homo sapiens for about 300 000 years. 
Spreadingoutside of Africa around 50 000 years back, and over time took over 
from theother human forms that lived in Europe and Asia before then.

Until about some thousands of years ago, all humanswere nomads - meaning they 
moved aroundaccording to seasons, to get food from the nature around them - 
following herdsof animals or moving to be close to water when it’s dry season, 
and spreadingto other areas when the season is more generally wet, etc.

Not livingin a permanent place makes large structures needed to make bigger 
machines hardto have. Once we started living in villages permanently, that 
allowed both more“spare time” (not spending time walking from one place to 
another), as well ashaving various more heavy duty machines and equipment to 
make other things,rather than only having “what you can bring with you”.

There’s alsoa huge amount of learning needed to get to sophisticated machines 
and otheradvanced technology. Learning that rely on people being able to 
exchange ideasat a distance, which pretty much requires a postal service or at 
least a way tosend letters.

The ways to produce metals and understanding moreof chemistry took a long time. 
About threethousand years ago, the first iron tools were starting to emerge, 
but only asvery “expensive” products - swords, arrowheads and some other 
weapons alongwith a few tools. More mass-produced metals didn’t appear until 
the last fewhundred years. You need metals to make almost all of the modern 
technology,including cars and electrical things.

A lot of technological development also depends on“previous inventions”. If you 
travelledback in time 1000 years and gave the smartest man in the village the 
exactrecipe for lithium batteries, he would have no useful way to make use of 
thatrecipe [and I’m completely ignoring any language issues, here - that WOULD 
be aproblem, but it’s also that there’s simply far too many steps between “the 
mostsophisticated technology available” and “making a lithium battery”

If you spendsome time studying the history of science and technology, there’s a 
clearprogression from basic machines and simple technology to modern machines 
andmodern advanced technology.

Q5         Is there scientific evidence to supportthe theory that life evolved 
from non-life through natural processes, such asevolution?

A5          Phil S. B.A. in Aerospace andAeronautical Engineering & Humanities 
(college minor), Embry-Riddle FL/AZ(Graduated 2013)Thu

Itdefinitely happened, and we know several ways it could have happened. Life 
and “non life” aren’tfundamentally different. What we call “life” is a set of 
mutuallycatalyzing chemical reactions, meaning reactions that make the 
catalysts theothers need as byproducts.

We also knowthat the emergence of life through abiogenesis (not evolution) is 
an aspect ofthe laws of the thermodynamics, specifically entropy. The chemical 
reactions that formed thebuilding blocks of life absorb energy from their 
environment which drivesentropy forward. You have to progress really far down 
the line to get toexothermic reactions that eventually became the base of 
organic metabolisms.

We also know that the evolution of life fromsimple to complex forms follows 
entropy.Complex life forms are slightly more resource and energy efficient than 
theequivalent mass of simple life forms while being massively more durable, 
sothere is selection pressure for life to become more complicated.
