Light bulb exponent-rules for the classroom

Exponent-rules are known to describe experimentally how the observables related to incandescent lamps alter with the change in the rated voltage. Pedagogical derivation of the rules for typical observables like the life, lumens, power, etc. in the case of vacuum bulbs is presented. This is achieved by assuming a steadystate operation of the bulb, parameterizing intrinsic properties of tungsten ...

100 Prisoners and a Light Bulb

We present a variety of different protocols for solving the “100 Prisoners and a Light Bulb” riddle, including explicit computations of average runtimes. This is an updated and corrected version of the original unpublished document released on December 5, 2002 at http://www.ocf.berkeley.edu/~wwu/. The protocols presented here can be attributed to many members of [wu::forums], an online forum of...

A Second UV “ Light Bulb ” behind the SN 1006 Remnant

A point X-ray source located 9 arcmin northeast of the center of SN 1006 has been spectroscopically identified as a background QSO, with a redshift of 0.335. The object is moderately bright, with magnitude V = 18.3. If its ultraviolet spectrum is typical of low-z quasars, this object will be a second (after the Schweizer-Middleditch star) source to use for absorption spectroscopy of material wi...

romantic education:reading william wordsworths the prelude in the light of the history of ideas

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
