How much does an elephant cost? Photo courtesy of The David Sheldrick Wildlife Trust. In their report, iworry estimated the raw-ivory value of a poached elephant to be $21,000. In contrast, a living elephant is worth more than $1.6 million over its lifetime, largely because of its eco-tourism draw. Can I own a baby elephant? […]
Is all green glass uranium?
Is all green glass uranium? Perhaps the most reliable way to identify the presence of uranium in the glass is to expose it in the dark to a source of ultraviolet light (e.g., a black light). If the glass glows a rich green color, it contains uranium. Why is depression glass called depression? Depression glass […]

Does lift increase with speed?
Does lift increase with speed? Drag versus speed. method of increasing lift is by increasing velocity if the AOA is held constant just short of the “critical,” or stalling, AOA (assuming no flaps or other high lift devices).
