It is well known that the number of elements has grown from four in the days of the Greeks to 103 at present, but the change in methods needed for their discovery is not so well known. Up until 1939, only 88 naturally occurring elements had been discovered. It took a dramatic modern technique (based on Ernest O. Lawrence's Nobel-prize-winning atom smasher, the cyclotron) to synthesize the most... more...

CHAPTER XVIII. JANET IN A NEW CHARACTER. On entering Lady Chillington's room for the second time, Janet found that the mistress of Deepley Walls had completed her toilette in the interim, and was now sitting robed in stiff rustling silk, with an Indian fan in one hand and a curiously-chased vinaigrette in the other. She motioned with her fan to Janet. "Be seated," she said, in the iciest... more...

Hansen was sitting at the control board in the single building on Communications Relay Station 43.4SC, when the emergency light flashed on for the first time in two hundred years. With textbook-recommended swiftness, he located the position of the ship sending the call, identified the ship and the name of its captain, and made contact. “This is Hansen on 43.4SC. Put me through to Captain Fromer.”... more...

PROLOGUE Though a lover of peace, Mr. Punch from his earliest days has not been unfamiliar with war.

The Star had been designed to be much more than a convenient transfer station for travelers and freight; for some... more...

LIFE OF NIKIAS. As it appears to me that the life of Nikias forms a good parallel to that of Crassus, and that the misfortunes of the former in Sicily may be well compared with those of the latter in Parthia, I must beg of my readers to believe that in writing upon a subject which has been described by Thucydides with inimitable grace, clearness, and pathos, I have no ambition to imitate Timæus, who,... more...

CHAPTER I. STATE OF WOMEN AMONG THE ARABS OF THE JAHILIYEH, OR THE "TIMES OF THE IGNORANCE." In that eloquent Sura of the Koran, called Ettekwir, (lxxxi.) it is said, "When the girl buried alive shall be asked for what sin she was slain." The passage no doubt refers to the cruel practice which still in Mohammed's time lingered among the tribe of Temîm, and which was afterwards... more...

PREFACE. Boswell did not bring out his "Life of Johnson" till he was past his fiftieth year. His "Journal of a Tour to the Hebrides" had appeared more than five years earlier. While it is on these two books that his fame rests, yet to the men of his generation he was chiefly known for his work on Corsica and for his friendship with Paoli. His admiration for Johnson he had certainly... more...

FOREWORD In all the welter of the tragic upheaval which is shattering institutions once thought immutable, condemning millions to physical death and awakening other millions to spiritual life, making staggering discoveries of unexpected human strength or weakness, thrusting men into fame one day or to oblivion the next, there has been nothing more dramatic than the sudden manifestation of the genius of... more...
