Tajikistan is landlocked, and is the smallest nation in Central Asia by area. It lies mostly between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°). It is covered by mountains of the Pamir range, and more than fifty percent of the country is over 3,000 meters (9,800 ft) above sea level. The only major areas of lower land are in the north (part of the Fergana Valley), and in the southern Kofarnihon and Vakhsh river valleys, which form the Amu Darya. Dushanbe is located on the southern slopes above the Kofarnihon valley.

In only his third career start, Kerry Wood struck out 20 batters against Houston on May 6, 1998. This is the franchise record and tied for the Major League record for the most strikeouts in one game by one pitcher (the only other pitcher to strike out 20 batters in a nine-inning game was Roger Clemens, who achieved it twice). The game is often considered the most dominant pitching performance of all time. Interestingly, Wood's first pitch struck home plate umpire Jerry Meals in the facemask. Wood then struck out the first five batters he faced. Wood hit one batter, Craig Biggio, and allowed one hit, a scratch single by Ricky Gutiérrez off third baseman Kevin Orie's glove. The play was nearly scored an error, which would have given Wood a no-hitter.
How many batters did Kerry Wood strike out against Houston?
20

In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
How many years prior to Planck's study had the scientific community first discussed black body radiation?
