Beam Reach – This is the fastest and easiest point of sail. The windis on the side of your boat (beam) and you’ll sail with your sails outhalf way. Broad Reach – On a broad reach you’ll be heading a bit further downwind, so you will have to let your sails out a bit more.

That course which a vessel makes good over ground, as a result of the effect of currents, tidal streams, and leeway caused by wind and sea. Categories: 9.1 VTS terms.

[′spēd ‚mād ′gu̇d] (navigation) The actual average speed in knots which was maintained in proceeding along the intended track to the ultimate destination or an intermediate point.

Course made good (C.M.G. or Course Over Ground) – the actual route taken to achieve the journey’s objecting measured over the ground. It is the resultant of the course steered and the effect on that course of any wind and tide.

At the optimum boat speed and angle to the wind, VMG is maximized, steering closer to the direction of the wind will reduce boat speed, while steering further away from the direction of the wind might give a higher boat speed, but at the cost of a larger deviation in heading, so less progress towards a mark.

A keel cat is stuck with the keels down, all the time-as such, there is no way to prevent the boat from “tripping over herself ” in storm-force conditions with large breaking cross seas. Off the wind a catamaran with fully raised daggerboards is much faster because wetted surface has been greatly reduced.

A sailboat would slide sideways with the wind if it did not have a centerboard or keel underneath the hull. The flow of water over the underwater surfaces creates lift, too—a sideways force countering the force of the wind. The combination of these forces pushes the boat forward.

Sailboats utilize both true wind and apparent wind. True wind always pushes a boat. If a boat sails absolutely perpendicular to true wind, so the sail is flat to the wind and being pushed from behind, then the boat can only go as fast as the wind—no faster.

Answer: Yes, I agree with Yudhistira, that mind is faster than the wind. If we think about a distance place, thing of person, immediately within a second we can get a vision in our mind.

Although the theory of special relativity forbids objects to have a relative velocity greater than light speed, and general relativity reduces to special relativity in a local sense (in small regions of spacetime where curvature is negligible), general relativity does allow the space between distant objects to expand …

The fastest synaptic transmission takes about 1 millisecond. Thus both in terms of spikes and synaptic transmission, the brain can perform at most about a thousand basic operations per second, or 10 million times slower than the computer.

The initial action potential accounts for 1 to 5 milliseconds and synaptic transmissions only take . 1 to . 5 milliseconds, so the bulk of that time is spent within the axons. This is consistent with research findings that the average individual neuron sends signals at around 180 kilometers per hour.

The speed of light (3×10^5 km/ second) is way faster than the speed at which the electrical signals in our brain propagate (~500km/ hour). Naturally, the thought process of the brain also takes place at the same pace. Hence, light always wins the race.

I’ve read that it takes about 100 to 250 milliseconds for the brain to complete one “thought”. Since you have 100 billion biological CPU cores all running in parallel, that would be roughly like one core running at something like 400 to 1,000 GHz.

Yet some scientists are convinced not only that AI will catch up with human beings, but that after computers reach our level of intelligence, they will soon surpass us. Because of these advantages, computers will be able to produce much more in-depth decision-making heuristics and statistics than the human brain.

To go further with AI we need to know more about human brain and take inspiration from the nature as well. The experts are predicting the term “technological singularity”-a hypothetical point which refers that AI smarter than humans will be created in the future that will solve every kind of human problem.

Yes, robots will replace humans for many jobs, just as innovative farming equipment replaced humans and horses during the industrial revolution. Factory floors deploy robots that are increasingly driven by machine learning algorithms such that they can adjust to people working alongside them.

Historically, technology has made us individually dumber and individually smarter—and collectively smarter. Technology has made us able to do more while understanding less about what we are doing, and has increased our dependence on others.

Computers enjoy other advantages over people. They have better memories, so they can be fed a large amount of information, and can tap into all of it almost instantaneously. Computers don’t require sleep the way humans do, so they can calculate, analyze and perform tasks tirelessly and round the clock.

Historically, technology has made us individually dumber and individually smarter – and collectively smarter. Technology has made us able to do more while understanding less about what we are doing, and has increased our dependence on others.

Abstract. The brain is the center of the human nervous system, controlling our thoughts, movements, memories, and decisions. Computers might be able to beat human brains every time when it comes to mathematical calculations, quantitative analysis, and game show questions, but that doesn’t mean they’re smarter overall.

2.5 million gigabytes

Here is where it gets really fun. A typical computer runs on about 100 watts of power. A human brain, on the other hand, requires roughly 10 watts. That’s right, your brain is ten times more energy-efficient than a computer.

Computer program scores 150 in IQ test, Swedish researchers demonstrate. In the 1800s, it meant that you were good at memorizing things, and today intelligence is often measured through IQ tests where the average score for humans is 100. Researchers in Sweden have created a computer program that can score 150.
