The uncertainty principle in quantum physics says that there is a limit to how precisely you can measure one of a pair of variables like position and momentum.
You can measure position precisely, but you cannot at the same time precisely measure momentum. Or . . . you can precisely measure momentum, but you cannot at the same time precisely measure position.

∙ 13y agoAccording to the principle of uncertainty, no instrument is 100% free from errors and in the physical world, due to various factors like human efficiency, complete perfection of instrument, measurement conditions, there is bound to be uncertainty and each value can be measured accurately upto the least count of the instrument which can always be decreased, and lesser the least count, more accurate is the measurement.

What is scientific measurement based on?
precision and accuracy
What is the scientific name for gram?
A gram is a scientific measurement, recognized by Systeme International, as 1/1000 of the SI standard unit for mass, the kilogram.
What are the three interrelated goals of the scientific enterprise?
Measurement (operational definition) -> Prediction -> Control
How do I convert the measurement 0.005 grams into scientific notation?
It is 5*10^-3 grams.
WHen you are making a batch of lemonade what scientific measurement are you using when you measure water?
[object Object]
What is meant by a mas measurement expressed in this form4.6g 0.2 g?
I suppose that you think to 4,6±0,2; 0,2 is the uncertainty of the measurement.
Why is significant figures important is measurement?
Significant figures are important in measurement because they determine how accurate a scientific claim can be. There always has to be a small amount of uncertainty in an answer, because no measurement or calculation is ever 100% absolute.
How do you calculate uncertainty?
There are several ways to calculate uncertainty. You can round a decimal place to the same place as an uncertainty, put the uncertainty in proper form, or calculate uncertainty from a measurement.
What is the percent uncertainty for the measurement given as 4.19m?
When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%
How do you calculate the uncertainty of data?
When involving in scientific experiments, it is very important to make measurement. In each and every measurement we take, say a length, time, angle etc. we have to use a particular instrument. As every instrument has a least count (also known as the minimal reading), there will be an uncertainty left. As an example, consider a measurement using a vernier caliper as at 10.00 cm, there will be an error of 0.01cm. If we do the same measurement by a meter ruler, there'll be an error of 0.1 cm, or 1 mm. Therefore the uncertainty of a particular measurement is dependent on the instrument it has been taken. As a convention we take the 1/2 of the least count for analog instruments and the least count for digital instruments as its uncertainty.
What is the uncertainty in the measurement for the speed of light?
The length of a meter.
How does quantum uncertainty differ from the uncertainty involved in a coin flip?
completely: coin is simple probability, quantum uncertainty is based on how increasing accuracy of measurement of one property of a tiny particle reduces the accuracy of measurement of another complementary property of the same particle. No probability there, just measurement limitations.
What is metrology the science of?
Scientifically speaking, metrology is the science of measurement. Unlike other scientific fields, metrology covers all levels of uncertainty in any field of science and technology.
Is the Uncertainty Principle a scientific law or theory?
Since it is called "the Heisenberg Uncertainty Principle" it is neither a scientific law nor a theory. It is a principle.
Does a measurement of 23.56mL has more uncertainty than a measurement of 23.5mL?
No, its more certain than 23.5 mL
What is the uncertainty in measurement when using a stopwatch to measure time?
o.1
Is there is any perfect measurement?
No, no measurement we can ever do will be entirely free of uncertainties. In some measurements the uncertainties might be negligible however. In any best precise & accurate measurement there will be minimum uncertainty equal to h/2pie, that's in accordance to Heisenberg's uncertainty principle.
