Philosopher Rebecca Newberger Goldstein discusses her new book "Plato at the Googleplex: Why Philosophy Won't Go Away."
The Copenhagen Wheel is a back wheel outfitted with a rechargeable battery that gives a bicycle rider a boost when going uphill. The battery is charged when riding downhill and braking.
The wheel is engineered and marketed by Superpedestrian, after being initially developed at MIT’s SENSEable City Lab as a research project sponsored by the mayor of Copenhagen.
Copenhagen Wheel co-inventor Assaf Biderman joins Here & Now’s Jeremy Hobson to discuss the technology, which he hopes will make commuting by bike easier and more attractive.
