QUESTION OF QUESTIONS


QUESTION OF QUESTIONS

Microsoft, Intel, HP, Dell, Apple, Google, Infosys, Wipro, Accenture, MindTree …….All big companies.. making whole lot of money. All are in the business of technology. Inventing new ways.Sometimes I feel overwhelmed by the speed of change. But what I am writing right now is not about change, its not even about technology or business. The question has been looming around in my head for almost a decade now.

Every human can relate to that question, It is in the very existence of human species. The question which many gr8 philosophers have been thinking and quoting about. Questions about success, life, god, happiness, satisfaction all have there own place in human mind, but they are all derived from this basic question.

Human evolution has seen many phases. From early humans and homo-sapiens to modern day information savy man. All related to different aspects of human development. It is the ability to think and ask questions and then find answers to them is the very fact which makes us evolve from one stage to other.

A person asked question about Lightning and he discovered Electricity.

A person asked question about apple falling and he discovered and defined the gravitation energy.

A person asked question about Life and he invented buddhism.

Every person in life has many questions to find an answer for. The ability to define this question and the journey of finding its answer is what makes everyone move.

Lets talk for a while about early humans. when there was no language. no civilization no rules, no regulations. All living equally in same conditions. How would they have been living. A human without words. A human without language. What sort of questions they are facing. To evolve these questions must have been defined and answered by someone.

Like the question of fire. The Human rubbing 2 stones against each other leading to friction and heat generation. Some questions are defined accidentally and some are defined by a conscious effort. The question in case of fire would have been:-

What will happen if I rub these 2 stones? Of course there was some element of curiosity in it. This question must have lead to huge rewards. The early human who generated fire must have been thought like a god or a daemon. Depending upon the overall outlook of the group they were living in and the way they exercised there power.The power of fire.. achieved through with an ability to define questions and then finding answer to it.

It is there in humans. The curiosity, the mindset of an explorer. The ability to take risks and go beyond the traditional means. The history has seen it many times. It is only the explorer, The Question asker, The curious who has always led to some innovation and revolution.

Not all questions answered were good for human evolution. Lets take an example of the question of dividing limited resources. How should the limited resources be divided? It was this question when answered gave birth ownership.

An early human group hunted a large elephant. Now they were faced with a challenge of how to divide it among a group of 10. Those who hunted that large animal. The question was Who should be given what size of the dead meat. All of them came up with different ways to divide it.

One said Divide it using the effort put in by everyone.One said divide it in equal proportions.

One said I should get the bigger piece because it was my idea to hunt it

One said I took the biggest risk so I should get a bigger piece

Similarly everyone came with his own answer to the very question of how to divide. What could have happened next-They all fought with each other and one person became victorious. Now it was up-to him to decide how to divide it. He took biggest for himself. and divided rest with some justified reason among others. or divided using his own personal choice just or unjust.They all voted and choose a decision taker. Now decision taker became the leader and he was forced to divide among the group using some justified reasons. But was difficult because one group had voted for him and other had not. So he gave bigger share to those who elected him as the leader.

Now since division was achieved by some means (Good or bad is out of scope for this article). came the sense of ownership. This is mine and this is not mine.

In essence it all started with one fact scarcity of resources. and the answer was to divide it and give everybody ownership for his piece.

Can you see it. Question leading to not only one answer but multiple answers and each answer creating its own by-discoveries like ownership, monarchy, democracy, politics, just, unjust, measures of size etc.

So to solve one question. A person had to solve a series of questions each leading to multiple inventions.

No-one knew what they were discovering or what they would discover in the process of answering a simple question.

We all know there are people who are great at making inventions and discoveries. While others are just following there routine lives. Not being able to invent and not being able to utilize this great human power of asking questions.

Coming back to the point of The gr8 question in my mind. The question is …. Where is the ability to ask questions, being an explorer , a curious person coming from. Is it the way in which we are built or there are more things to it. I may find an answer someday. How can we cultivate this ability of asking questions. This is the greatest human ability which is only responsible for separating us from the others. Ability to have a thought process. And can this ability be generated in machines or computers?

Summary:-

The Great ability is to ask questions and then undertake a journey to answer that question.

Every evolution was lead by some invention or discovery which was an answer to some question

Develop and cultivate the ability to ask questions.

All companies small or big are looking for explorers, question asker and people who are curious enough to figure things out and lead the next wave of revolution

DokuWiki is a standards compliant, simple to use Wiki, mainly aimed at creating documentation of any kind. It is targeted at developer teams, workgroups and small companies. It has a simple but powerful syntax which makes sure the datafiles remain readable outside the Wiki and eases the creation of structured texts. All data is stored in plain text files – no database is required.

Torque, Horsepower, Bore and Stroke


Torque, Horsepower, Bore and Stroke

While these topics can get very scientific here is a overview that you will find useful to understand the characteristics of a particular engine. This can assist you to make an informed choice based on scientific grounds when comparing two motorcycles.

Torque

Torque is the ability of the engine to continue to twist (rotate) the rear wheel with great force. Torque has nothing to do with speed. Maximum torque is not to be found at the highest revs but somewhere below that – perhaps as much as 25%. Because lower revs are involved, the rear wheel is less inclined to spin and loose traction – an important issue when riding your bike up a steep gravel road.

Horsepower

Horsepower is the ability of your engine to move your bike forward at a certain speed – the higher the speed, the shorter the time taken, the greater the horsepower needed.
Every engine has its own characteristics of torque and horsepower – something you as the rider can only learn with experience and hopefully, not too much trial and error! In the example specs given below the engine develops the most torque at 4000 rpm before it starts to drop again. By contrast the horsepower available increases steadily all the way to 5000 rpm.

Practically what does this mean for me the rider? Let us take the BMW F650 as an example. The bike’s manual gives the following technical specs

Maximum permissible rpm 7500
Maximum rated capacity (horsepower) 35 kW at 6500 rpm
Maximum torque 57 N.M. at 5200 rpm
From this we can see that the difference between max torque and max power is 1300rpm – quite a big gap that we must utilise for different conditions.
Consider these two scenarios below based on the specs in the table above. (Your bike will have its own characteristics – consult your manual)

Scenario One

You are traveling along on your motorcycle on a country road behind a long truck doing about 85km. The oncoming traffic is heavy. Things are going to be tight. You will need maximum torque for fast acceleration and maximum horsepower for the necessary speed to take you past and beyond.

The gap you are waiting for arrives! You check your rev counter and it is sitting around 3000rpm. The specs tell us that 5200rpm delivers the maximum torque. The situation demands the maximum. You change down a gear and the revs shoot up drawing on the torque available. You open the throttle up and gun the bike into the gap.

The bikes speed and revs climb quickly. There is not much point taking the revs past 6500 as the horsepower begins to level off after that (the maximum rated capacity). You change to a higher gear and the revs drop back towards the 5200 mark allowing you to again draw on the torque to give added impetus to the bike’s acceleration.

Again the bike’s speed and revs climb quickly. As you do not have another gear to change to you keep the throttle wide open gunning for 7000 rpm. Here the bike is using its horsepower to cover greater and greater distance in a shorter and shorter time period (distance over time i.e. speed)

By now the truck is a speck in your mirror and it’s time to relax and check to see that your passenger was not left somewhere behind on the tarmac!

Scenario Two

You are travelling up a steep gravel-road mountain pass on a 4 x 4 route. You do not want the motorbike to falter and equally you do not want to go too fast. Thus you change to whatever gear that maintains the revs around 4500rpm and maintains the desired speed. This still gives you some extra torque to use if you need it (from 4500 to 5200 rpm)

If both the speed and revs begin to increase you can change to a higher gear and bring them back down. If the speed and revs begin to drop below 4000rpm it is time to change to a lower gear and bring them back up. At all times the idea is to keep the bike in striking distance of the maximum torque level (sometimes called the powerband – yes, confusing as it has nothing to do with horsepower)

The great thing about this topic is that we naturally know all of this just by doing. Listening to the engine and feeling the amount of power still left untapped is the real teacher in this instance.

Bore and Stoke

The combined attributes of bore and stroke makes motorcycle engines very different. Bore is the diameter of the piston (or the diameter of the inside of the cylinder). Stroke is the maximum distance that the piston travels up and down inside the cylinder

Example: The Ducati 999R has a bore of 104mm and a stroke of 58.8mm while a Harley Davidson Road King Classic has a bore of 95.3mm and a stroke of 111.3mm. These big differences in bore and stroke makes the first a superbike with enormous horsepower and the latter a cruiser with a lot of torque.

To make comparisons between bikes we divide the bore by the stroke. If the resultant number is more than 1, then the bike is horsepower orientated and must be operated at high revs. If the number is less than 1 then the bike is torque orientated and is operated at low revs. In the case of the HD Road King above the number is 0.86, therefore a cruiser. The Ducati by comparison yields a number of 1.76, a number comparable to a formula one racing car. The average result for motorcycles is generally around 1.2

NOTE: A motorcycle is not only a product of bore and stroke as many other factors come into play e.g. number of cylinders, gearbox, suspension, rake angle etc. Nevertheless the trend is clearly visible in the table below.

Ducati 999R 104 58.8 1.76 Sportbike
Honda CBR 600 F4 67 42.5 1.57 Sportbike

Suzuki Intruder M800 83 74.4 1.1 Cruiser
Victory Kingpin 101 102 0.99 Cruiser
Vespa PX 150 Scooter 57 58 0.98 Commuter
Buell Ulysses 88.9 96.8 0.91 Enduro offroad
Harley Davidson Fat Boy 95.3 101.6 0.93 Cruiser
Harley Davidson Road King Classic 95.3 111.3 0.86 Cruiser
* Other factors is design in fact make this BMW motorcycle a capable off road touring bike as well.

NOTE. Older cruiser engine designs have the longest stroke measurement. . Engines with long strokes have a lower compression ratio, poorer fuel economy, poor exhaust emissions, greater friction and have crankshafts that are subject to greater destructive forces. For this reason modern performance cruisers like the HD V-Rod have moved quite far up the table as a result of their shorter strokes.
