Back in 1802, when Napoleon still cherished dreams of conquering Britain, one of his engineers proposed the construction of a tunnel under the English Channel.

But Britain's decision to join the European Common Market brings to an end the historic British policy of "splendid isolation" from the Continent. Last week, as British Transport Minister Ernest Marples flew to Paris to open the first...
...Commission's long-planned underground experiment in the peaceful applications of nuclear energy. Southeast of Carlsbad, N.Mex., a shaft has already been sunk 1,200 ft. in the ground to penetrate a thick formation of rock salt. From the shaft's bottom, a 1,116-ft. horizontal tunnel leads into the salt and curves back on itself in a giant hook. At the tip of the hook a small (5-kiloton) bomb will be exploded in December. If all goes well, the explosion will seal the horizontal tunnel by collapsing the hooked end, and it will leave...
...implantation is done in one operation. Surgeon Chardack opens the chest to get the electrode into the heart wall and leads the connecting wire through a tunnel under the skin to another incision in the abdomen, just to the left of the navel. He sets the pacemaker on a bed of abdominal muscle. Only 2 by 3 by ½ in., it is so compact that the patient can bend double without feeling it. The battery should last four to five years, and failure is not fatal. The heart jogs along until the battery is replaced...
Inside the underground tunnel, workers are laying the key parts in place and testing them individually. Every large electronics firm has contributed parts for the mammoth accelerator, which has its own water-cooling system and will tax Cambridge power for 1000 kw/sec during experiments...
...circular tunnel and the experimental hall are shielded by concrete walls ten feet thick. To avoid radioactive dangers, doors seal automatically and a 40-ton crane operated by remote control moves equipment...
