Биография Д.И. Менделеева

it{he} has written to it{her}:

Friends united not only predilection for chemistry - they were in many

respects similar - with identical passion were given work, and by

something, with a head were immersed in new business. It was to tell the

truth, shown at them differently. Mendeleyev all was given passion and did

not cool down, while in it{him} the spark decayed even. It{he} did not

undertake something another, was not convinced yet that here it{he} has

learned{has found out} and has taken all. It{he} was sincerely pleased the

affinity with as counted his{its} unusually talented person and thanked

destiny that she{it} has reduced them.

And was similar to noisy, sparkling fireworks which it{he} is skilful

to prepare and prepared always , with love. It{he} perfectly painted in

oils and drew, is skilful to mould and engrave - not speaking that it{he}

played on many tools, - was the chemist and the composer. And how to know,

whether from this friendship with went then hobby for art. Probably, all

the same many-sided nature - it really inevitable display of the big

talent. The person, great really, probably, cannot enclose all force and

all talent in one channel. A life, as if being afraid to lose invaluable

particles of human talent, does not allow it{him} to make it.

And in Petersburg Mendeleyev suddenly feels sharp pleasure of

returning. It{he} has understood, that all years missed this city. Now

it{he} not one here: sister Olga has returned. Together with the husband

decembrist Basarginym she{it} was in the long Siberian reference. Here, in

its{her} house, Mendeleyev even more often meets with - she{it} is

pleasant to it{him}, but it{he} badly knows women and is not confident that

is necessary to follow advice{council} of the sister and to marry. It{he}

wants to find out - whether they can with understand each other, but every

time perplexed stops: no, it is visible, has not stuck to hasten, hurry

destiny. Let all develops how is, without any efforts.

It{He} trusts, that so it will be better. Then suddenly inflow of

despair - it{he} doubts of itself, in the and writes the letter. No, not

the letter, and cry from the heart is born{carried} to the sister to Moscow

(her{it} have carried away for the period of an affair). And that answers:

And it{he} concedes.

And in fact that is strange: it{he} was the person with strong

character, is skilful to stand for itself and God forbid to someone it{him}

to offend, and here suddenly it{he} has conceded. From what? It{he} knew,

that has been in love only, instead of liked. And married. To it{him} it

was not indifferent? Probably, no. But it{he} trusted, that if has left ,

for it{her} it would become valid impact. And it{he} could not reconcile to

it. It{he} is not skilful to hurt anothers.

In three years at the son was born. Dmitry Ivanovich together with the

friend the professor Iljinym buys from the ruined prince small , nearby to

Klin, moves there and with starts to be engaged in an agriculture.

However, the hobby it was not casual: Mendeleyev for a long time missed

the nature.

In it is good it{him}. It{he} walked much, exploited, strove on the

skilled field, and in the evenings quite often met herd going from a

pasture. It{he} very much loved all this. But business not only in it.

Experiences which it{he} puts, serve one purpose. His{its} science should

to people concrete advantage{benefit}. Here, in , it{he} brings up in

itself(himself) other attitude{relation} to business: work of the scientist

should not be outside of communication{connection} with practice. And right

at the end of the life it{he} will recollect these days and will write

about experiences: ., it appears, when it{he}

started to think of the future.

For now still it{he} walked with the son on glades, with boyish passion

played on a lawn in a croquet, pottered on a current, collected just the

bought thresher. Also it was visible, that here, in , it{he} feels like

itself(himself), freely and happily.

So thought, looking at him{it}, his{its} wife. She{it} thought, that so

will be always, that Dmitry Ivanovich has understood, at last, where and in

what his{its} happiness. From one only these ideas the wave of silent

pleasure overflew her{it}.

But she{it} was mistaken. In its{her} husband the great scientist at

that time ripened. It{he} did not think of it. She{it} simply did not

understand it.

And again Petersburg. The idea on chemical affinity of elements which

has come within students, again excited it{him}. It{he} has been absolutely

firmly convinced, that by all means should exist certain law - imperous,

relentless which defines{determines} this affinity or distinction of the

elements occupying the world.

How many up to him{it} was attempt - naive, far-fetched - find this

law, obeying it{him} to place all elements on harmonous system... At that

time chemists have opened and 64 elements, knew their

nuclear weights so the material for work already was. There was no only a

person who would manage to penetrate into this secret laying as it seemed,

somewhere nearby and nevertheless inaccessible.

French chemist Shankurtua searched for law, having arranged elements on

the screw cutting put on worth cylinder. All is vain.

English chemist Njulends, the person, probably, the refined nature,

tensely searched for a solution with the help of music. It{he} trusted,

that those parities{ratio} which exist between elements, are similar to

parities{ratio} between musical tone and his{its} octave. construct the

system, it is artificial pushing in it{her} elements, them under those

sizes which itself and has prepared. The system was, but the system of

elements was not. it was necessary to go through minutes when chairman of

the British congress of scientists has asked it{him}, not hiding irony:

whether

Mendeleyev looked in the essence of the phenomena and did not try to

search for any external communication{connection} uniting all elements in

the base of a universe. It{he} tried to understand - that them connects and

that defines{determines} their properties. Mendeleyev has arranged elements

on increase of their nuclear weight and began to grope law between nuclear

weight and other chemical properties of elements. It{he} tried to

understand ability of elements to attach to itself(himself) atoms of

relatives or to give the.

It{He} has armed with lots of cards and has written on one party{side}

the name of an element, and on other - it nuclear weight and formulas of

his{its} some major connections. It{he} again and again shifted these

cards, stacking them on properties of elements. And in his{its}

consciousness any new laws emerged, and it{he} with the familiar excitement

previous to opening, cautiously moved ahead further and further. Hours

it{he} sat, having declined above the table, again and again peering into

records, and felt, how the head and as eyes were dimmed with a shivering

veil started to be turned from a pressure{voltage}...

Speak, that in dream to it{him} there has come inspiration and that at

night to it{him} as, in what order it is necessary to spread out those

cards that all has lain in the places under the law of the nature. Can be.

The brain of the person always is awake. But there was Mendeleyev to this

enlightenment years! It{he} moved ahead intelligently, beforehand planning

and expecting each next step. Can, and there was that inspiration, but

it{he} cannot be named casual.

Mendeleyev has found communication{connection} even between the most

unlike elements. It{he} has found out, that properties of elements if them

to place in ascending order nuclear weights, through correct intervals

repeat. Mendeleyev understood: accident it could not be. Then it{he} has

made last - deciding step: has arranged all elements also on groups, having

united in separate families of close relatives. It{he} so clearly saw

harmony of the system created by him{it}, that, having noticed absence of

an element between aluminium and the titan, has left to it{him} an empty

seat. Such empty cells{cages} it was necessary to leave two more.

Mendeleyev's system allowed it{him} to expect opening.

First of them has followed in four years. The element for which

Mendeleyev has left a place and properties which nuclear weight it{he} has

predicted, has suddenly appeared! Young French chemist Lekok has sent the

letter in the Parisian academy of sciences. In it{him} it was spoken: . But the most amazing still was necessary.

Mendeleyev has predicted, still leaving for this element a place, that

his{its} density should be 5,9. And asserted{approved}: the element open

by him{it} has density 4,7. Mendeleyev, and in eyes not seeing new it and

is more surprising than elements - themes, declares, that the French

chemist was mistaken in calculations. But also appeared : it{he} assured,

that was exact. This dispute resembled any game in which participated .

This magician carried Russian name.

Hardly later after additional measurements it was found out: Mendeleyev

was unconditionally right. The first element, filling an empty place in the

table, has named gallium in honour of the native land of France. And to

anybody then has not occurred to name it{him} of the person who has

predicted existence of this element, person who has once and for all

predetermined a way of development of chemistry. It was made by scientists
