Victor Twersky

**Victor Twersky** (1923 – 17 Kasım 1998), ışıktan radara, sonardan yeryüzündeki sismik dalgalara kadar radyasyon saçılması ile alâkalı her nev'i kuramın en önemli öncülerinden biri olarak bilinen ve bu anlanlarda 100'den fazla yayını bulunan Amerikalı fizikçi.

## Hayâtı
1943'te City College of New York'tan lisans derecesi, 1948'de Columbia Üniversitesi'den Yüksek Lisans ve 1950'de de New York Üniversitesi'den doktora aldı. 1950-1953 yılları arasında Courant Enstitüsü Matematik Bilimleri'nde ; 1953-1966 yılları arasında Mountain View, California'daki 'nda kıdemli bilim adamı ve kariyeri boyunca birçok defa Stanford Üniversitesi Matematik Bölümünde ziyaretçi öğretmen olarak çalıştı.

### Akademik araştırma alanları
Twersky  yıllarında, saçılma teorisi ve tanılayıcı uygulamalar konularında ve 1979-80 yıllarında ise saçılma teorisinin biyofizik uygulamaları alanlarında çalışmak üzere yaşamı boyunca İki kez  olmaya hak kazandı.

1969-70 yıllarında  İleri Araştırmalar Merkezi'nde *Yoğun Dağılımlar'da Çoklu-Saçılma amaçlı "Boyutsal Bağlılaşım" ()* konusunda danışman olarak araştırmalar yürüttü.

'nde Matematik, İstatistik ve Bilgisayar Bilimleri Bölümü'nde 1966-1990 yılları arasında Profesör olarak hizmet verdi. Burada uzun yıllar *Uygulamalı Matematik Program Komitesi Başkanı* olarak görev yaptı. 1990 yılının Aralık ayında 'dan emekli oldu.

Victor Twersky, İlmî tekâmüle yönelik Amerikan derneği, IEEE ve 'nun da *Fellow* üyesi idi.

### Ölümü
17 Kasım 1998 tarihinde 'da öldü. Her yıl anısına  tarafından bir Uygulamalı Matematik öğrencisine *Victor Twersky Hatıra Bursu* verilmektedir.
