Several of these problems are theoretical: they involve observed phenomena that existing theories seem incapable of explaining. Others are experimental: they concern theories that do not lend themselves to testing or phenomena that cannot be investigated in greater detail. What are several of the most prominent unsolved problems? Discuss

Tuk-tuks are small vehicles used for urban transport. They are especially popular in the traffic-congested and densely populated cities of Southeast Asia, such as Bangkok. Often employed as taxis, tuk-tuks usually have sheet metal bodies with canvas roofs and drop-down or removable sides. They rest on three wheels—one in front and two in back—have a small cabin for the driver, and seating for up to three passengers. Rather than steering wheels, tuk-tuks possess what steering mechanism? 
In the spring of 1914, the Colorado National Guard machine-gunned and torched a tent colony in Ludlow, where striking coal miners and their families had been living after being evicted from their company-owned homes some months earlier. Nineteen people, most of them women and children, were killed. For the next 10 days, the strikers attacked nearby mines and battled mine guards and militia. Federal troops were needed to put an end to the violence. Which side eventually prevailed in the strike?
