Taking Measure With Hardware and Software

The researchers who founded National Instruments Corp switched from building their own equipment to beefing up other people’s.

“You could start a company.” That offhand comment by Jim Truchard got Jeff Kodosky and Bill Nowlin thinking. Within days, Truchard and his two employees at the Applied Research Laboratories (ARL) at the University of Texas at Austin (UT) decided to give it a go. That was in February 1976. By May, the trio had incorporated. Today, National Instruments Corp has annual Sales topping $425 million, employs more than 3100 people, sells some 1500 hardware and software products, and, for five years running, has been rated by Fortune magazine as one of the 100 best companies to work for.

  At ARL, Truchard headed an underwater acoustic measurements lab. “I had about two dozen different projects, all the way from basic acoustics to pragmatic testing of military sonar beam formers,” he says. Truchard went into science because of Sputnik. “I was right on the cusp of that movement. We were all taking Russian and physics,” he says. He earned bachelor’s and master’s degrees in physics and did his PhD — on a nonlinear parametric acoustic receiving array — in electrical engineering, all at UT. Kodosky and Nowlin both worked part-time for Truchard while enrolled at UT. Nowlin earned a master’s in electrical engineering and Kodosky, who has a bachelor’s in physics from Rensselaer Polytechnic Institute, worked toward a PhD; he drifted between theoretical high-energy physics and computer science but did not complete the degree.

Physics intuition

Both Kodosky and Truchard point to their physics training as playing a role in their success with National Instruments. Says Truchard, “Acoustical measurements are fairly tricky, and it happens to be a smaller area where you didn’t have off-the-shelf equipment. You had to build equipment. That background, and the measurements themselves, created a basis.” What’s more, he adds, “the physics background helps create good intuition. I think having solved differential equations and learned about gradients, you know how things are going to work out. I’ve always felt it helped me develop intuition about business.”

  In leaving academic research, says Kodosky, “we took a giant step back from what we were working on. ARL was cutting edge. Now it was customers who were doing the interesting experiments.” Still, he and Truchard say they have more impact on science by supplying tools than they would have had as researchers. “We can have a nonlinear effect on the productivity of the science and engineering community. There is plenty of anecdotal evidence that our virtual instrumentation can make people 5 to 10 times as productive,” Kodosky says. “I personally would find it frustrating [to do research] because it’s slow, but dropping by a customer’s site every couple of years is fun. We live vicariously through them.”

O senhor

Carta a uma jovem que, estando em uma roda em que dava aos presentes o tratamento de você, se dirigiu ao autor chamando-o “o senhor”:

Senhora:

Aquele a quem chamastes senhor aqui está, de peito magoado e cara triste, para vos dizer que senhor ele não é, de nada, nem de ninguém.

Bem o sabeis, por certo, que a única nobreza do plebeu está em não querer esconder sua condição, e esta nobreza tenho eu. Assim, se entre tantos senhores ricos e nobres a quem chamáveis você escolhestes a mim para tratar de senhor, é bem de ver que só poderíeis ter encontrado essa senhoria nas rugas de minha testa e na prata de meus cabelos. Senhor de muitos anos, eis aí; o território onde eu mando é no país do tempo que foi. Essa palavra “senhor”, no meio de uma frase, ergueu entre nós um muro frio e triste.

Vi o muro e calei: não é de muito, eu juro, que me acontece essa tristeza; mas também não era a vez primeira.

A escolha do tratamento que se queira atribuir a alguém geralmente considera as situações específicas de uso social. A violação desse princípio causou um mal-estar no autor da carta. O trecho que descreve essa violação é:

Em um experimento, preparou-se um conjunto de plantas por técnica de clonagem a partir de uma planta original que apresentava folhas verdes. Esse conjunto foi dividido em dois grupos, que foram tratados de maneira idêntica, com exceção das condições de iluminação, sendo um grupo exposto a ciclos de iluminação solar natural e outro mantido no escuro. Após alguns dias, observou-se que o grupo exposto à luz apresentava folhas verdes, como a planta original, e o grupo cultivado no escuro apresentava folhas amareladas.



Ao fim do experimento, os dois grupos de plantas apresentaram
