Rov qab mus rau yav dhau los: Laser patent thiab Intel Pentium processors tab tom los (22/3/2021)

Niaj hnub no, lasers yog ib feem ntawm peb lub neej thiab cov thev naus laus zis uas nyob ib puag ncig peb txhua hnub. Nws cov hauv paus hniav hnub rov qab mus rau qhov pib ntawm lub xyoo pua xeem, tab sis lub laser raws li ib tug ntaus ntawv yog thawj patented tsuas yog nyob rau hauv 1960, thiab nws yog qhov kev tshwm sim uas peb yuav nco qab nyob rau hauv hnub no tsab xov xwm. Hauv ntu thib ob ntawm cov ntsiab lus keeb kwm niaj hnub no, peb yuav tham txog Pentium I processor los ntawm lub tuam txhab Pentium.

Patented Laser (1960)

Thaum Lub Peb Hlis 22, 1960, Arthur Leonard Shawlow thiab Charles Hard Townes tau tso cai thawj zaug laser patent. Lub patent officially belongs rau Bell Telephone Laboratories. Lo lus Laser yog ib lub ntsiab lus rau lub sij hawm Lub teeb Amplification los ntawm Stimulated Emission ntawm Radiation. Txawm hais tias lub hauv paus ntsiab lus ntawm lub laser twb tau piav nyob rau hauv thawj ib nrab ntawm lub xyoo pua xeem los ntawm Albert Einstein nws tus kheej, tus thawj tiag tiag functional laser yog tsim los ntawm cov kws txawj hais saum toj no tsuas yog nyob rau hauv 1960. Plaub xyoo tom qab, Charles Townes yog ib tug ntawm peb cov kws tshawb fawb uas tau txais. Qhov Nobel nqi zog rau kev tshawb fawb tseem ceeb hauv kev lag luam quantum electronics, uas tau coj mus rau kev tsim kho oscillators thiab amplifiers raws li lub hauv paus ntsiab lus ntawm masers (emitting microwaves es tsis txhob lub teeb) thiab lasers.

Here Comes the Pentium (1993)

Thaum Lub Peb Hlis 22, 1993, Intel tshaj tawm tias nws tau pib faib nws cov Pentium microprocessor tshiab. Nws yog thawj tus processors los ntawm Intel nrog rau qhov cim no, uas yog thawj zaug los qhia txog lub cim thib tsib ntawm Intel processors, tab sis nws thiaj li dhau los ua ib hom khoom nrog nws tus kheej lub cim lag luam. Lub moos zaus ntawm thawj Pentium yog 60-233 MHz, plaub xyoos tom qab Intel tau qhia nws cov Pentium II processor. Cov txheej txheem kawg hauv Pentium series yog Pentium 2000 thaum Lub Kaum Ib Hlis 4, ua raws li Intel Pentium D.
