Lebedev started his scientific 1) …… as a “Junior scientific collaborator”. However,
soon he headed a research team and 2) …… a research laboratory, “Laboratory of
Electric Networks”. In 1933 he published a monograph, “Stability of Parallel
Operation of Electric Systems”, 3) …… with his colleague A.S. Zhdanov. In 1935
Lebedev was awarded a professorship and in 1939 he submitted thesis of doctoral
dissertation and received 4) ……, “Doctor of Technical Sciences”, thus skipping
preliminary degree, “Candidate of Technical Sciences” (PhD). 47 At the end of the
war, in 1945, Lebedev created the first electronic analogue computer for solving
systems of ordinary differential 5) …… - a “common calculation tool” at the
electrical power engineering. Already before the war Lebedev demonstrated interest
in facilitated computations. Lebedev also experimented with binary arithmetic.
Intensive development of power engineering in civil area, as well as progress of
nuclear physics researches and beginning rocket construction caused urgent need in
precise 7) …… facilitated computations. Some information already 8) …… about the
first foreign electronic computing machines. Later, leading scientists of Kiev such as
academician V.M. Glushkov or O.A. Bogomolets - the younger and mathematician
S.G. Krein (who was the first programmer for Lebedev), remembered that it was M.A.
Lavrentyev who 9) …… him to start practical work on electronic computers.
Lavrentev himself learned about them from commercial advertising in some technical
journals, which O.A. Bogomolets had brought from some of his trips to Switzerland.
In the autumn 1948 Lebedev 10) …… regular work on creation of the Small
Electronic Computing Machine (MESM). First of all, the complete set of necessary
mathematical operations to be performed by the computer should be defined. For that
11) …… Lebedev invited to Kiev leading experts, physicist A.A. Dorodnitsin and
mathematician K.A. Semendyaev. By the end of 1949, all design calculations were
completed and the basic structure of the computer 11) ……. In 1950 MESM was
assembled in 12) …… of Kiev - Feofania (Theofania).
IV. Answer the following questions in a written form.
1. Who was MECM conceived by?
2. How was MECM called at first?
3. What devices were added to it?
4. What department did S.A. Lebedev head at the Institute of Energetics in Kyiv?
5. When did Lebedev direct his laboratory towards creating MECM?
6. When was the machine put into operation?
7. Why can the creation of MECM be called a feat?
