  <div class="box blue" id="blueBox">From 1889 to 1891, Schorr worked as an assistant editor of Astronomische Nachrichten, at the observatory at Kiel.[2] In 1892 Schorr became observer (observator) at the Hamburger Sternwarte (Hamburg Observatory) Schorr was the director of the Hamburger Sternwarte (Hamburg Observatory). The former director George Rümker had started the movement of the observatory to the outer parts of Hamburg but went serious ill and died in 1899. After Rümker's death Schorr became director. The building of Germany's second largest observatory in Hamburg-Bergedorf at that time became his task. The new observatory opened in 1912. Schorr's main interests had been star positions (astrometry), proper motion of stars and solar eclipse observations. Schorr initiated many catalog projects (most popular is the AGK2). From 1905 to 1928 Schorr organized 8 big expeditions to observe solar eclipses at different parts in the world. At 7 he took part himself.</div>
  <div class="box green" id="greenBox">Instrumentals consists of Clams Casino's reconstructions of backing tracks he originally produced for rappers such as Lil B and Soulja Boy.[3] An electronic mixtape,[4] it features illbient, glitchbeat, and chillwave styles.[3] Some of the mixtape explores a more traditional hip hop sound. Its second half touches on bouncy basslines ("She's Hot"), dubstep-influenced, low-end grind ("Brainwash by London"), and vocal looping similar to the production of Kanye West ("Cold War").[1] Instrumentals appropriates Casino's previous hip hop beats into moody compositions, which are characterized by melodramatic drum crescendos and melancholic electronic sounds.[4]</div>
