The only good way that I am aware of to range using an optical sight is the way the navy used to do it. They had a calibrated reticle at the intermediate image. This allow one to measure the angular subtense of a target. If the size of the target is known then you can calculate its range.
This worked fine at sea because the dimensions of most enemy ships were known. (This method was very common before radar and laser rangefinders.) On land you may be able to estimate the size of various objects such as houses (ten feet per story) or people or cars or even trees.

In the wake of the Greener Gadgets conference held last week in New York City, review site Retrevo released results from a survey looking at how much green factors into people’s gadget buys. Unsurprisingly, the answer was not much. But there might be a silver lining. A gadget can be considered “green” if an effort has been made to keep its negative environmental footprint to a minimum along its supply chain. Major factors include energy consumption, waste production, the ability for its components to be recycled, and the toxicity of the materials used to make it. Considering that most gadgets are assembled from parts made by many different companies around the world, and travel extensive distances, it takes a lot of time and attention to make a green phone, music player, appliance, etc. And of course there are shades of green. Here are some of the key results from the Retrevo survey: When asked whether they feel guilty not buying a green gadget – 42 percent said no, because they don’t…
Yeah: how insurance pays for treatment for most people (and how insurers, both private and public set payment schedules on treatments, which was already alluded to upthread), the problems of adverse selection vs frankly predatory recission, … OK, more plainly I am trying to say the problem is NOT just that “healthcare costs too much”.
If the suspected impurities are at all soluble, there is no way you can find out the solubility of the pure material, without purifying the drug. Any physical measurements you carry out are bound to refer to the mixture that you have.
So, can you see 1,500 ft with those new "Binoculars?"…
