karyakshetr

satyeandranath bos ne apana kary kshetr vijnan ko chuna. jab bos aur saha kolakata vishvavidyalay mean padhate the, us samay bos ne socha ki vijnan mean kuchh naya karana chahie. bos aur saha ne nishchay kiya ki padhane ke sath-sath kuchh samay shodhakary mean bhi lagayeange. shodh ke lie ne-ne vicharoan ki avashyakata hoti hai isalie bos ne gibbas aur plaank ki pustakean padhana shuroo kiya. us samay vijnan samagri adhikaanshat: fraansisi ya jarman bhasha mean hoti thi. atah vyakti ko in bhashaoan ka jnan hona avashyak tha. bos ne in bhashaoan ko n keval bahut jaldi sikha balki unhoanne in bhashaoan mean likhi kavitaoan ka baangla bhasha mean anuvad bhi karana praranbh kar diya tha.

aianstain aur bos

[[chitr:Bose-and-Einstein.gif|thumb|aianstain ke sath satyeandranath bos]] ab bos ne apane tariqe se plaank ke niyam ki nayi vyutpatti di. bos ke is tariqe ne bhautik vijnan ko ek bilakul hi nayi avadharana se parichit karaya. bos ne is shodhapatr ko 'philas aauphikal maigajin' mean prakashan ke lie bheja parantu is bar unake shodhapatr ko asvikar kar diya gaya, jisase bos hatotsahit hue kyoanki unaka manana tha ki yah vyutpatti unake pahale ke karyoan se kahian zyada tarkik thi. phir bos ne sahasik nirnay liya. unhoanne is shodhapatr ko aianstain ke pas barlin bheja, is anurodh ke sath ki ve is shodhapatr ko padhean evan apani tippani dean aur yadi ve ise prakashan yogy samajhean to jarman jarnal 'Zeitschrift fur Physik' mean prakashan ki vyavastha karean. is shodhapatr ko aianstain ne svayan jarman bhasha mean anudit kiya tatha apani tippani ke sath 'Zeitschrift fur Physik' mean agast 1924 mean prakashit karavaya. aianstain ne is shodhapatr ke sambandh mean ek postakard bhi bheja tha jo bos ke lie bahut adhik upayogi siddh hua.

bos-aiansatain saankhyiki siddhaant

grahoan aur unake sambandhoan ko samajhane ke lie nyootan ke gurutvakarshan siddhaant ki avashyakata hoti hai. usake anusar sansar ki har vastu apane as-pas paee jane vali doosari vastu ko apani or akarshit karati hai. jaise soory grahoan ko, prithvi chandrama ko. yah siddhaant jyadatar jagahoan par to lagoo hota hai, lekin bahut si aisi jagahean haian, jahaan par yah kam nahian ata. yadi ham gaisoan ke anuoan ki gati ki bat karean, to vahaan par yah niyam asahay ho jata hai. gaisoan mean asankhy prakar ke anu pae jate haian, jo sadaiv gatishil rahate haian. inaki gatishilata ka gais ke dab aur tap se ek khas sambandh hota hai. gaisoan ke in anuoan ki gati ko samajhane ke lie ganit ke ausat ke niyam ka sahara liya jata hai. ise samajhane ke lie maiksavel aur boltjamain ne jis ganitiy siddhaant ki vyutpatti ki, use saankhyiki ke nam se jana jata hai. saankhyiki ausat ke ganit ki bat karati hai. adhunik bhautik vijnan mean isaki avashyakata kadam-kadam par paee jati hai.

jis vyakti ki medha ko aiansatain jaise vaijnanik ne n sirph svikara balki usake sath apana nam bhi jo da, us vyakti ko nobel puraskar n milana kafi saval kh de karata hai. yah bat isalie bhi mahatvapoorn hai ki jyadatar vaijnanikoan ka manana hai ki bhautik vijnan par jitana asar ‘bos-aianstain saankhyiki’ ka p da hai, utana asar to shayad ane vale samay mean higs bos aaun ka bhi n ho.

aantarrashtriy vaijnanikoan se sanbandh

aktoobar, 1924 mean satyendranath yoorop pahuanche. bos pahale ek varsh peris mean rahe. phraans mean rahate hue bos ne socha ki kyoan n 'rediyodharmita' ke bare mean 'maidam kyoori' se tatha 'm aauris di brogli' (luee di brogli ke bhaee) se 'eks-re' ke bare mean kuchh sikha jae. maidam kyoori ki prayogashala mean bos ne kuchh jatil ganitiy gananaean to kian parantu rediyodharmita ke adhyayan ka sapana adhoora rah gaya. m aauris di brogli ke sath bos ka anubhav achchha raha. brogli se inhoanne eks-re ki nee takanikoan ke bare mean sikha. thumb|250px|satyeandranath bos aktoobar, 1925 mean bos ne barlin jane ka vichar banaya jisase ve apane 'mastar' se mil sakean. bos aianstain ko 'mastar' kah kar sambodhit karate the. vastav mean bos aianstain ke sath kam karana chahate the. jab bos barlin pahuanche to unhean nirasha huee kyoanki aianstain shahar se bahar ge hue the. kuchh samay ke bad aianstain vapas ae aur bos se mulakat ki. bos ke shabdoan mean 'yah ek dilachasp mulakat thi. unhoanne sabhi tarah ke prashn poochhe jaise apako (bos) ek nee saankhyiki ka vichar kaise aya aur isaka kya mahattv hai adi.' bos ko aianstain ke sath kam karane ka avasar to nahian mila par unase huee kee mulakatoan se bos ko bahut labh hua. aianstain ne unhean ek parichay patr bhi diya jisane bos ke lie bahut sare daravaze khol die.

plaank ke niyam se prativad

satyeandr nath bos ne Planck’s black body radiation law ka gahan adhyann kiya aur blaik b aaudi redieshan ki photon gais ke roop mean pahachan ki. unhoanne meks plaank jinhoanne kvantam mekeniks ki rachana ki, ke blaik b aaudi rediyeshan niyam mean lait kvaanta ya photon gais ko lekar prativad tha jisako lekar ainsatain bhi asahamat the. yah samay tha 1920 ka jab kvantam mekeniks mean yah gutthi ki tarah thi, kvantam mekeniks ke vikas ho to raha tha lekin gati behad dhimi thi kyoanki kahian n kahian plaanks ke niyam ko agale charan tak le jana tha. usi samay bharat mean dhaka vishvavidyalay ke ek prophesar satyedr nath bos, kvantam mekeniks ke adhyann mean ae aur unhoanne 1924 ko ek char prishth ke riserch pepar likha jisaka shirshak tha ‘Planck’s Law and the Hypothesis of Light Quanta (1924)’ jo aj m aaudarn kvantam mekeniks aur kanoan se ju di kisi bhi khoj, adhyayan ka adhar hai. satyeandr nath ka yah riserch pepar age chalakar bos–aianstin stetiks aur bos–aianstin kanadenaset (ek tarah ki stet aauph maitar) ke roop mean badala jisaki khoj satyeandr nath bos aur aianstin ne khud milakar ki. unake bare mean likha gaya ki “Bose entered the quantum arena and set out to derive Plancks law treating radiation as a gas consisting of photons. What Bose had essentially introduced was a new counting rule for the states of a gas of photons – or the quanta of light – that explained Plancks law of thermal radiation at one stroke.”

bos ka shodhapatr

1924 mean satyeandr nath bos ne ek shodh patr taiyar kiya jisaka nam unhone ‘Planck’s Law and the Hypothesis of Light Quanta’ diya. vaijnanik paribhasha mean kahe to “ Bose derived Planck’s quantum radiation law without any reference to classical physics by using a novel way of counting states with identical particles.” sadharan taur par kahe to bos ne apane tariqe se plaank ke niyam ki nayi vyutpatti di. bos ke is tariqe ne bhautik vijnan ko ek bilakul hi nayi avadharana se parichit karaya. bos ne kvantam fiziks stadi ne ek nee niv rakh thi jo us samay se lekar aj tak sabhi kanoan ke khojoan ka adhar rahi haian jisaka taza udaharan hiangs bos aaun kan ki khoj hai. 1924 mean jab bos ne ‘Planck’s Law and the Hypothesis of Light Quanta’ ko taiyar kar liya to ise unhone duniya ki jani mani vijnan shodh patrika ‘philas aauphikal maigajin’ mean prakashit hone ke lie bheja. lekin unaka shodhapatr prakashit nahian hua. kuchh samay bit janate ke bad bos ne phir aianstin ko sidhe yah shodhapatr bhejane ka ek mahatvapoorn nirnay liya aur barlin mean sidhe ‘Planck’s Law and the Hypothesis of Light Quanta’ ko bheja aur aianstin ko is par vichar prakat karane aur ise jarman mean anuvad kar ‘Zeitschrift fur Physik’ vijnan patrika mean prakashit karane ka nivedan kiya. unaka patr is prakar tha

I have ventured to send you the accompanying article for your perusal and opinion. I am anxious to know what you think of it. You will see that I have tried to deduce the coefficient 8pv2/c3 in Plancks Law Independent of classical electrodynamics, only assuming that the elementary regions in the phase-space has the content h3. I do not know sufficient German to translate the paper. If you think the paper worth publication I shall be grateful if you arrange for its publication in Zeitschrift fur Physik. Though a complete stranger to you, I do not feel any hesitation in making such a request. Because we are all your pupils though profiting only by your teachings through your writings. I do not know whether you still remember that somebody from Calcutta asked your permission to translate your papers on Relativity in English. You acceded to the request. The book has since been published. I was the one who translated your paper on Generalised Relativity.

bos ka shodh behad mahatvapoorn tha aur aianstin ne is bat ko samajha. is shodhapatr ko aianstin ne svayan jarman bhasha mean anudit kiya tatha apani tippani ke sath ‘Zeitschrift fur Physik’ mean agast 1924 mean prakashit karavaya. aianstin ne is shodhapatr ke sambandh mean bos ko ek postakard bhi bheja tha jo bos ke lie us samay ek khas chiz thi.

aianstin se mulaqat

[[chitr:Satyendra Nath Bose Postage Stamp.jpg|thumb|satyendr nath bos ke samman mean jari dak tikat]] 1924 ke bad bos aianstin ke sidhe sanpark mean ae aur aianstin ne bhi bos ke sath kary karane ki ikchha ichchha jataee. 1924 ke bad bos bharat ke bahar jakar shodh kary karana chahate the, bos ne vishesh agrah kar aianstin se prashansa patr ko dhaka vishvavidyalay mean sammalit kar do varsh ke lie avakash prapt kiya aur yoorop ke lie ravana huye. aktoobar, 1924 mean satyendranath yoorop pahuanche. bos pahale ek varsh peris mean rahe. phraans mean rahate hue bos ne ‘rediyodharmita’ mean ‘maidam kyoori’ ke sath tatha ‘m aauris di brogli’ (luee di brogli ke bhaee) mean ’eks-re’ shodh mean sath mean kam kiya. maidam kyoori ki prayogashala mean bos ne kuchh jatil ganitiy gananaean to kian parantu rediyodharmita ke shodh par adhik kary nahian kar paye. m aauris di brogli ke sath bos ka anubhav behad achchha raha. brogli se inhoanne eks-re ki nee takanikoan ke bare mean sikha. aktoobar 1925 mean ve barlin ge aur akhir mean aianstin se pahali bar vyaktigat taur par mile. yah mulaqat bos aur aianstin donoan ke lie khas thi. isi samay bos – aianstin stetiks aur bos – aianstin kanadenaset ( ek tarah ki stet aauph maitar ) sankalpana huyi. bos – aianstin stetiks adhyann ke dauran p aaul diyarik, aianstin aur satyeandr nath bos ne sath mean kary kiya. isi samay ek vishesh tarah ki kanoan ki khoj huyi. is kan ka nam satyeandr nath bos ke nam par rakhane ka phaisala liya aur kan ka nam bos aaun rakha gaya.

bos aaun aur pharmiyan

aj bhautiki mean kan do prakar ke hote haian ek bos aaun aur doosare pharmiyan. bos aaun yani phot aaun, gluaaun, gej bos aaun (photon, prakash ki mool ikaee) aur pharmiyan yani kvark aur lept aaun evan sanyojit kan prot aaun, nyootr aaun, ilektr aaun ( charj ki mool ikaee) . yah vartaman bhautiki ka adhar haian. vartaman mean bos – aianstin stetiks adhar haian staiandard m aaudal aauph partikal fiziks. vartaman mean jo bhi anu bhautiki se ju de haian sabhi ki sabhi shodhoan ka adhar kahian n kahian bos – aianstin saankhyiki haian. ek vaijnanik ne bos ke bhautiki mean sthan ke bare mean kaha haian “You Don’t Know Who He Was? Half the Particles in the Universe Obey Him! ”

kolakata vishvavidyalay

bos sanh 1926 se 1945 tak dhaka mean rahe parantu shodhapatroan ka prakashan kram pahale ki bhaanti nahian raha. aisa shayad isalie raha kyoanki bos ki dilachaspi ek samasya se doosari samasya mean parivartit hoti rahi. sanh 1945 mean bos kolakata vapas a ge aur kolakata vishvavidyalay mean bhautiki ke prophesar pad par niyukt ho ge.

shaantiniketan mean

bos 1956 mean kalakatta vishvavidyalay se sevanivritt hokar shaanti niketan chale ge. shaanti niketan kavi ravindranath taigor dvara sthapit kiya gaya tha. taigor satyendr nath bos se achchhi tarah parichit the tatha unhoanne apani pustak 'vishv parichay' bhi bos ko samarpit ki thi. parantu purane logoan ne bos ko pasand nahian kiya jisase bos ko bahut nirasha huee aur 1958 mean unhean kalakatta vapas lautana p da. isi varsh bos ko r aauyal sosayati ka phailo chuna gaya aur isi varsh unhean rashtriy prophesar niyukt kiya gaya. bos agale 16 barasoan tak (mrityuparyant) is pad par bane rahe.

kala aur sangit premi

[[chitr:Satyendra Nath Bose playing Israj.jpg|thumb|isaraj bajate hue satyendr nath bos]] satyendr nath bos lalit kala aur sangit premi the. bos ke mitr batate the ki unake kamare mean kitaboan, aianstin, raman adi vaijnanikoan ke chitr ke alava ek vady yantr yasaraj hamesha rahata tha. bos isaraj aur baansuri bajaya karate the. parantu isaraj to kisi visheshajn ki tarah bajate the. bos ke sangit prem ka dayara lok sangit, bharatiy sangit se lekar pashchath sangit tak phaila hua tha. pro. dhurajati das bos ke mitr the. jab pro. das bharatiy sangit par pustak likh rahe the, tab bos ne unhean kafi sujhav die the. pro. das ke anusar bos yadi vaijnanik nahian hote to vah ek sangit guru hote.

bos ki prerana

ni:sandeh aianstain hi bos ke jivan ki prerana the. kahate haian jab bos ko aianstain ki mrityu ka samachar mila tha to vah bhavuk hokar ro p de the. aianstain vijnan ke kshetr ke mahanayak the aur bos unamean eeshvar ki tarah shraddha rakhate the.

nidhan

san 1974 mean bos ke samman mean kalakatta vishvavidyalay ne ek aantarrashtriy sangoshthi ka ayojan kiya. jisamean desh-videsh ke kee vaijnanik sammilit hue. is avasar unhoanne kaha "yadi ek vyakti apane jivan ke anek varsh sangharsh mean vyatit kar deta hai aur aant mean use lagata hai ki usake kary ko saraha ja raha hai to phir vah vyakti sochata hai ki ab use aur adhik jine ki avashyakata nahian hai." aur kuchh hi dinoan ke bad 4 faravari, 1974 ko satyendr nath bos sachamuch hamare bich se hamesha ke lie chale ge.
