They can, but it is very difficult and dangerous. We can relatively easily get measurements from Doppler radar, but that always has a margin of error and it cannot measure wind at ground level.
We can get exact measurements by placing probes inside tornadoes, which is far more difficult. To start, a scientist must get to a spot on a road ahead of the tornado, deploy the probe, and get away before the tornado hits. This is harder than it may sound, especially since the time you have is usually measured in seconds. Even when the probe is deployed in time, tornado paths are hard enough to predict that the tornado often misses the probe. There is also the problem of building a probe that can withstand the winds of a tornado. Several probes over the years have been able to hold up to some rather strong tornadoes, but it is doubtful the equipment could survive the very strongest. One scientist, Tim Samaras, managed to create a probe that might have withstood 250-300 mph winds, but tornadoes that strong are rare and Samaras was killed by a tornado before he could successfully deploy it in a violent tornado.
They can, it's just difficult. The only way to get an exact measurement of the wind speed you actually have to get a probe inside of the tornado. Such a task requires driving out in front of a tornado, dropping the probe, and getting out before the tornado hits. In many cases the probe is not in exactly the right place, and tornado misses, if there is an opportunity to place the probe at all. It is possible to get an approximate measurement of a tornado's wind speed by positioning a mobile Doppler radar near it. Such units are limited, however, as they can only measure the component of the wind velocity that is directly toward or away from the radar and cannot measure winds at ground level. Doppler radars are also expensive, so relatively few of them exist. On top of these limits, the radar still has to be in the right place at the right time, which is also hard to do. As a result, the vast majority of tornadoes go without their wind speeds being measured.
There is no known exact upper limit to tornadic wind speeds. The fastest wind speed ever recorded in a tornado was a gust to 302 mph about 100 feet off the ground. However, wind measurements in tornadoes are fairly rare, so other tornadoes likely had faster winds. The upper limit is probably somewhere between 300 and 350 mph.
To describe a property without using measurements is to make a qualitative description. This type of description focuses on the characteristics, features, and qualities of the property rather than its exact numerical measurements.
Tornadoes typically travel from southwest to northeast in the Northern Hemisphere and from northwest to southeast in the Southern Hemisphere. However, their exact path and direction can vary depending on various atmospheric conditions such as wind speeds and directions.
An exact science is a field of science that rigorously tests its hypothesises with precise experiments, predictions and measurements. For this reason, both Physics and Chemistry - but not biology - are considered as exact sciences.
Tornadoes and twisters are the exact same thing.

Scientists understand that tornadoes are a type of small but violent windstorm with both intense rotating winds and very strong updrafts. Tornadoes form from strong thunderstorms, but scientists only partially understand the exact mechanisms of their formation. (see below links for more information). Scientists know that tornadoes vary in strength, size, forward speed and duration. Although stronger tornadoes tend to be larger and longer lasting, this is not always the case. These tornadoes can cause anything from minor damage to total destruction. Tornadoes usually follow a straight path, but can make turns while others have followed meandering paths. Tornadoes often occur in outbreaks, where multiple tornadoes form from one storm system within a day or two. The strongest of tornadoes often occur in such outbreaks. Some tornadoes break down to produce multiple suction vortices, which produce narrow, curved swaths of damage that is more severe than that from the rest of the tornado. The are call multiple vortex or multivortex tornadoes. Many of the strongest tornadoes are multivortex.
Scientists are still not sure how exactly a thunderstorm produces a tornado or why one storm will produce a tornado while another won't. They are still not sure what determines how strong or how large a tornado will be or how long it will last.
The exact measurements of a Humvee in inches is 184.5 inches long by 86.5 inches wide. It also has a height of between 77 and 79 inches.

Usually in the centre. Check with brand and model of the shower to be installed for exact measurements or check the rough-in manual for the EXACT shower for proper measurements.
Scientists must rely on estimates when they cannot obtain exact numbers.
In the years 1950-2010 Texas has had 7903 confirmed tornadoes.
So that they get exact amounts, making experiments worthwhile
They cannot be because of errors that can be made by the measurer, calibration of instruments.
It is important because PRECISE means exact, and exact measurements are important because it tells you the actual measurement of an object, other than to tell you an estimate, not knowing the exact measurement of that object
