Question: In September 2014, Professor Stefan Grimm, of the Department of Medicine, was found dead after being threatened with dismissal for failure to raise enough grant money. The College made its first public announcement of his death on 4 December 2014. Grimm's last email accused his employers of bullying by demanding that he should get grants worth at least 200,000 per year. His last email was viewed more than 100,000 times in the first four days after it was posted. The College has announced an internal inquiry into Stefan Grimm's death. The inquest on his death has not yet reported.

Answer: 4 December 2014
Question: Some independent stereo manufacturers including JVC, Pioneer, Kenwood, Alpine, Sony, and Harman Kardon also have iPod-specific integration solutions. Alternative connection methods include adapter kits (that use the cassette deck or the CD changer port), audio input jacks, and FM transmitters such as the iTripalthough personal FM transmitters are illegal in some countries. Many car manufacturers have added audio input jacks as standard.
Try to answer this question if possible: What audio integration feature has become standard on many car models?
Answer: audio input jacks
Question: Chopin also endowed popular dance forms with a greater range of melody and expression. Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form. His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance-floor equivalents.
Try to answer this question if possible: How many polonaises were published while Chopin lived?
Answer: seven
Question: There are 29 isotopes of copper. 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper; they both have a spin of 32. The other isotopes are radioactive, with the most stable being 67Cu with a half-life of 61.83 hours. Seven metastable isotopes have been characterized, with 68mCu the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by , whereas those with a mass number below 64 decay by +. 64Cu, which has a half-life of 12.7 hours, decays both ways.
Try to answer this question if possible: What is the half life of the copper isotope 67Cu?
Answer:
61.83 hours
