Good for advanced estimating

This is a very good book for advanced estimators.
If you are trying to get into estimating go with Means.
If you want to accurately calculate time to construct a major piping project this will cover you very well.

I'm still playing with this thing. For the price it's excellent. Regardless of the price, this thing is very accurate. I still use it at times to get ideas of surface temps for things. I even use it to get a quick idea of the temp of the home. Just shoot it at the ceiling and the floor and split the difference.

Having tables of digitized values for Treloar's experiments was worth the price of the book.  Often abstract-looking tensor symbols are often written in index notation; very helpful.

Easy to use.  Provides estimates for paint, wall paper, tile, carpet and concret.  Accurate for paint.  I have not used it for anything else but no reason to suggest it will not also be accurate.

I bought this book for a course. It's easy to use when you want to estimate the cost of a building construction.

I bought this item recently to (more) precisely weigh some small DIY mechanical parts. While still waiting for the calibration weight set (ordered separately)I measured a pile of ~30 nickels. Each one weighed between 4.89 and 5.08 grams when measured on this scale and a random selection of 20 weighed 99.60g.

I calibrated it with a 100g weight from a calibration set I also purchased from Amazon, and compared the other weights of the calibration set with their printed value - all were very close to their value (typically +/-0.01g or so, although more than half were dead on) except for the 5g weight, which measured 5.08g.  After calibration, the nickels had the same range of values, but repeatability through on-off cycles seems to be about 0.02g. Nice (unexpected even) results for a ~$12 scale, but this is not a lab scale ;)

This scale is sensitive enough that your breathing can affect the readings, and your table should be level.

An advanced calculator for your desk, seems to be better bang for your buck than competitors. I've enjoyed many of the advanced options, especially for networking, binary/hex conversion, and seeing all the numbers I've added up.

As someone who's just getting into baking seriously, this has been useful for it.  It's also great for measuring out my portions for lunch and dinner, so I know how much I'm actually eating instead of just estimating the size of a chicken breast or pile of pasta.

This is a pricey but versatile calculator.  Yes, there are better, more advanced calculators out there for the advanced mathematics and scientific user.  And yes, this item should be priced much lower than it is, considering it has been on the market for a long time.  However, for use in an academic setting, consider that there exists a lot of  teaching materials out there in the classrooms, as well as activities, that are built around this model.  So, because of that, this model has survived all this time.

I bought this calculator to use in a Corporate Finance class.  Calculating Time Value of Money problems with this was much easier than using the BA II Plus.  The inputs are easier to enter, without having to memorize long sequences of key strokes.

Your instructor and the class activities will most likely dictate which brand and model of calculator to purchase, rather than a reviewer's recommendations.  However, one bit of advice I can give you is very important to remember:  Please, use regular 1.5v alkaline batteries should you purchase this model.  The rechargeable batteries, with their 1.2v, will not be enough to give you a clear display.  A set of four batteries will last a very long time.  However, it would not be a bad idea to carry a spare pack of 4 in your briefcase or backpack.  You would not want to run out of battery in the middle of an important exam.  This calculator, unlike the more basic models, will not run on solar power.

I recently replaced this guy with a refractometer, but this was actually a nice quick way for the amateur to estimate the alcohol by using the "no-brainer" scales on the side.  I'm keeping it hanging around as a backup.  Very good product.

Recommended book for years of observations. Requires
some elementary understanding, so it's a great and valuable resource
after some observing experience.

I have a long history of using these books from Craftsman Books when estimating work. I find them very helpful, and the price was right from Amazon.

Very nice to have baselines for temperature and Specific Gravity.
Very well made, though the calibrations for the temperature was quite difficult to read due to its size but there's a "green zone" that tells you when the readings are within a safe range. Works the same way with SG reading.

I bought this thermometer for food science and am happy with the results. I can measure the outside temperature of food as well as the grill/pan it's cooking in. It even appears to "look" through a water bath to take the temperature of bagged food poaching in a sous vide water bath. The twin laser pointers converge at about 12-14" to find the sweet-spot at which the temperature gun works best -- allowing you to precisely point at particular items to get accurate measurements of each. I went with the model that reads higher temperatures, expecting that at times I may want to get readings off broilers, grills and other hot things e.g. my wife's body temperature reads a degree lower than normal, but she's still pretty "hot".

Photo caption: Temperature taken from the base of the Anova precision cooker = 55C, surface temp of semi-frozen food = 52.8C at the time of this reading (note how both laser pointers have converged into a single dot to measure temperature at the optimal distance).

Got this unit to do quick distance calcs for wire runs inside buildings most of the time.  The addition feature allows to shoot several hallways at a time for a very accurate calculation.  For longer distances, I have noticed the unit must be absolutely still so I find placing it on top of my ladder works well or even on top of a box sitting on the floor.  There seems to be a spot on the bottom to mount to a tripod but for what i am using it for, that would take a lot more time to set up.

ISBN 1482204584 (A Handbook of Statistical Analyses using R, 3rd ed.) is an excellent compact reference on R not for beginners in programming or statistics even though it starts with the brief introductions to R and data analysis. They are followed by chapters on inference, variance, regression, density, partitioning, smoothers, longitudinal data, comparisons, meta-analysis, principal component, scaling, and clustering, as in&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/the-2nd-ed/dp/1420079336/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">the 2nd ed.</a>, and additionally on quantile regression and missing values not in the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/the-2nd-ed/dp/1420079336/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">the 2nd ed.</a>.

The text full of useful examples well teaching R to solve problems of explained statistical techniques and involved math described individually in separate chapters.  The descriptions are systematic explanations in the tutorial style: introduction of data, R example to purify data, and R example to find the data significance.  The book is well printed on good paper, but the relatively flimsy soft covers are prone to creasing. It could be complemented by&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Introduction-to-Scientific-Programming-and-Simulation-Using-R/dp/1466569999/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Introduction to Scientific Programming and Simulation Using R</a>.

This statistics chart contains quite a bit of information. I haven't used it yet it in my Elementary Statistics class yet (4 weeks in), but have a feeling I'll need to later.
